On rockchip platforms (e.g. RK3588/RV1106), the dwc3 drd port
can be designed with Type-A interface, and when the drd work
as device mode, the vbus may be set to always on (RK3588 EVB2)
or the vbus is supplied by host.
The current code sets the desired sw_mode to device (peripheral)
when the dwc3 controller is initialized with no usb cable/device
connected, this sets the usb2 phy stay in normal mode. For device
mode with vbus always on (RK3588 EVB2), it's not standard design，
we can allow the usb2 phy to stay in normal mode to detect whether
usb device is connecting to host. But for device mode with vbus
is supplied by host (RV1106 EVB1), we can use the vbus to detect
whether usb device is connecting to host, in this case, the usb2
phy needs to be put in suspend mode by default.
In order to make the usb2 phy in suspend mode by default for
Type-A interface when drd in device mode and vbus isn't always
on, we only set the desired sw_mode to peripheral if the state
of EXTCON_USB it true.

The otg port on Rockchip platforms can be designed in
three different hardware circuits with Type-A interface.
1. RK3588 EVB2 Type-A OTG0 port with vbus is controlled
by gpio, and vbus is always in high level.
2. RV1106 EVB1 Type-A OTG port with standard vbus designed
that vbus isn't always on, and just depends on the OTG
mode, that is, when the OTG port work as device mode,
the vbus is supplied by Host, when the OTG port work
as host mode, the vbus is always on.
3. RV1103 EVB1 Type-A OTG port has no vbus pin, and we set
the utmi_bvalid of phy to high from GRF software control.
In this case, the utmi_bvalid status register is in low
level, so we can't use the utmi_bvalid status to check the
utmi_bvalid for RV1103.
In order to support the above three application scenarios
for Type-A OTG port, especially phy runtime suspend control
for device mode, we need this patch.
With this patch, we can fix the following two issues:
1. RV1106 EVB1 Type-A OTG port can't enter phy suspend if
no usb cable connected.
2. RV1103 failed to switch to device mode by "otg_mode"
node, because phy enter suspend unexpectedly.

RV1103 USB has no VBUS pin and we set the utmi_bvalid of phy
to come from PERI_GRF_USBPHY_CON2[14], and at the same time
set the utmi_bvalid to high by default. This case like VBUS
pin always on high level, so we need to add "vbus-always-on"
property for RV1103 USB OTG port.

Page owner of pages used by page owner itself used is missing on arm32
targets. The reason is dummy_handle and failure_handle is not initialized
correctly. Buddy allocator is used to initialize these two handles.
However, buddy allocator is not ready when page owner calls it. This
change fixed that by initializing page owner after buddy initialization.
The working flow before and after this change are:
original logic:
1. allocated memory for page_ext(using memblock).
2. invoke the init callback of page_ext_ops like page_owner(using buddy
allocator).
3. initialize buddy.
after this change:
1. allocated memory for page_ext(using memblock).
2. initialize buddy.
3. invoke the init callback of page_ext_ops like page_owner(using buddy
allocator).
with the change, failure/dummy_handle can get its correct value and page
owner output for example has the one for page owner itself:
Page allocated via order 2, mask 0x6202c0(GFP_USER|__GFP_NOWARN), pid 1006, ts 67278156558 ns

Emulate NMIs on systems where they are not available by using timer
interrupts on other cpus. Each cpu will use its softlockup hrtimer
to check that the next cpu is processing hrtimer interrupts by
verifying that a counter is increasing.
This patch is useful on systems where the hardlockup detector is not
available due to a lack of NMIs, for example most ARM SoCs.
Without this patch any cpu stuck with interrupts disabled can
cause a hardware watchdog reset with no debugging information,
but with this patch the kernel can detect the lockup and panic,
which can result in useful debugging info.

On RK3588 platform, the USB Host port may miss disconnect
falling edge irq which is used to detect usb device plug in.
This always happens in the following two cases:
1. For RK3588 ARM PC, boot system from U Disk which connected
the USB2 Host port (EHCI & OHCI Controller);
2. For RK3588 EVB, increase the disconnect filer counter to
0xF4240 in the reg USB2PHY_GRF_DIS_CON. That is, the
disconnect rising/falling irq filter time is set to 10ms
depend on the 100MHz pclk.
In this case, we can clear the host_disconnect state depend
on the linestate irq which also means that an usb device is
connecting to the port.
