Fix the issue that when the FW size is 32K+, it will fail for the download
process because of the incorrect index.
When firmware patch length is over 32K, "dl_cmd->index" may >= 0x80. It
will be thought as "data end" that download process will not complete.
However, driver should recount the index from 1.

Realtek RTL8822BE BT chip on ASUS X420FA cannot be turned on correctly
after on-off several times. Bluetooth daemon sets BT mode failed when
this issue happens. Scanning must be active while turning off for this
bug to be hit.
bluetoothd[1576]: Failed to set mode: Failed (0x03)
If BT is turned off, then turned on again, it works correctly again.
According to the vendor driver, the HCI_QUIRK_RESET_ON_CLOSE flag is set
during probing. So, this patch makes Realtek's BT reset on close to fix
this issue.

Realtek bluetooth may not work after reboot:
[ 12.446130] Bluetooth: hci0: RTL: rtl: unknown IC info, lmp subver a99e, hci rev 826c, hci ver 0008
This is a regression introduced by commit 26503ad25d ("Bluetooth:
btrtl: split the device initialization into smaller parts"). The new
logic errors out early when no matching IC info can be found, in this
case it means the firmware is already loaded.
So let's assume the firmware is already loaded when we can't find
matching IC info, like the old logic did.

The Realtek RTL8723BS and RTL8723DS chipsets are SDIO wifi chips. They
also contain a Bluetooth module which is connected via UART to the host.
Realtek's userspace initialization tool (rtk_hciattach) differentiates
these two via the HCI version and revision returned by the
HCI_OP_READ_LOCAL_VERSION command.
Additionally we apply these checks only the for UART devices. Everything
else is assumed to be a "RTL8723B" which was originally supported by the
driver (communicating via USB).

The UART settings are embedded in the config blob. This has to be parsed
to successfully initialize the Bluetooth part of the RTL8723BS (which is
an SDIO chip, but the Bluetooth part is connected via UART).
The Realtek "rtl8723bs_bt" and "rtl8723ds_bt" userspace Bluetooth UART
initialization tools (rtk_hciattach) use the following sequence:
- send H5 sync pattern (already supported by hci_h5)
- get LMP version (already supported by btrtl)
- get ROM version (already supported by btrtl)
- load the firmware and config for the current chipset (already
supported by btrtl)
- read UART settings from the config blob (part of this patch)
- send UART settings via a vendor command to the device (which changes
the baudrate of the device and enables or disables flow control
depending on the config)
- change the baudrate and flow control settings on the host
- send the firmware and config blob to the device (already supported by
btrtl)
Sending the last firmware and config blob download command
(rtl_download_cmd) fails if the UART settings are not updated
beforehand. This is presumably because the device applies the config
right after the firmware and config blob download - which means that at
this point the host is using different UART settings than the device
(which will obviously result in non-working communication).

This prepares the btrtl code so it can be used to initialize Bluetooth
modules connected via UART (these are found for example on the RTL8723BS
and RTL8723DS SDIO chips, which come with an embedded UART Bluetooth
module).
The Realtek "rtl8723bs_bt" and "rtl8723ds_bt" userspace Bluetooth UART
initialization tools (rtk_hciattach) use the following sequence:
1) send H5 sync pattern (already supported by hci_h5)
2) get LMP version (already supported by btrtl)
3) get ROM version (already supported by btrtl)
4) load the firmware and config for the current chipset (already
supported by btrtl)
5) read UART settings from the config blob (currently not supported)
6) send UART settings via a vendor command to the device (which changes
the baudrate of the device and enables or disables flow control
depending on the config)
7) change the baudrate and flow control settings on the host
8) send the firmware and config blob to the device (already supported by
btrtl)
The main reason why the initialization has to be split is step #7. This
requires changes to the underlying "bus", which should be kept outside
of the "generic" btrtl driver.
The idea for this split is borrowed from the btbcm driver but adjusted
where needed (the btrtl driver for example needs two blobs: firmware and
config, while the btbcm only needs one).
This also prepares the code for step #5 (parsing the config blob) by
centralizing the code which loads the firmware and config blobs and
storing the result in the new struct btrtl_device_info.

The Bluetooth parts of RTL8723D and RTL8723B share the same lmp
subversion, thus we need to check both lmp subversion and hci revision
to distinguish the two. The same situation is true for RTL8821A and
RTL8821C. Accordingly, the selection code is revised.
To improve maintainability, a new id_table struct is defined, and an
array of such structs is constructed. Adding a new device can thus be
as simple as adding another value to the table.
