1.Hdmirx DMA caused NOC abnormal pending during hot-plug operation,
resulting in system crash.Detect signal change as soon as possible
and reset hdmirx controller in FIQ to avoid hdmirx DMA exception.
2.Add hdmirx DMA reset operation when HDMI is unplugged and hdmirx
DMA is off.

Support call same level initcall async in kthread.
Introduce kernel parameter "initcall_nr_threads" control how many threads.
initcall_nr_threads default is 0, which disable intcall async.
initcall_nr_threads=-1, auto selected the number of threads.
Save boot time about 29ms on rk3126-bnd-d708 board.

RV1103 doesn't have VBUSDET pin for the usb phy to
detect the USB VBUS, and the default status of bvalid
is inactive(low level), it cause the dwc3 controller
fail to start usb device connection, so it needs to
set bvalid to high by grf for RV1103.

This patch enable the USB configs for basic device and
host functions.
With this patch, it also enable CONFIG_CONFIGFS_FS because
the USB Gadget F_FS depends on it.
I use size cmd to calculate the increased static memory.
before:
MODULE BYTES
kernel/drivers 1212734
kernel/fs 699540
after:
MODULE BYTES
kernel/drivers 1506379
kernel/fs 712940
And if we disable the CONFIG_DEBUG_FS, it can save 11441 Bytes
for xhci-debugfs driver.

In a typical read transfer, start completion flag is being set after
read finishes (notice ipd bit 4 being set):
trasnfer poll=0
i2c start
rk3x-i2c fdd40000.i2c: IRQ: state 1, ipd: 10
i2c read
rk3x-i2c fdd40000.i2c: IRQ: state 2, ipd: 1b
i2c stop
rk3x-i2c fdd40000.i2c: IRQ: state 4, ipd: 33
This causes I2C transfer being aborted in polled mode from a stop completion
handler:
trasnfer poll=1
i2c start
rk3x-i2c fdd40000.i2c: IRQ: state 1, ipd: 10
i2c read
rk3x-i2c fdd40000.i2c: IRQ: state 2, ipd: 0
rk3x-i2c fdd40000.i2c: IRQ: state 2, ipd: 1b
i2c stop
rk3x-i2c fdd40000.i2c: IRQ: state 4, ipd: 13
i2c stop
rk3x-i2c fdd40000.i2c: unexpected irq in STOP: 0x10
Clearing the START flag after read fixes the issue without any obvious
side effects.
This issue was dicovered on RK3566 when adding support for powering
off the RK817 PMIC.

* LPCM: BPCUV insertion by hw
* NLPCM/HBR: BPCUV insertion from stream
when BPCUV is from stream, we should not enable hw channel
status override which will replace CS with the hw one.
This fixes DD+ bitstream.
when BPCUV generated from HW, PBIT_FORCE_EN should be set
for Parity bit calculated internally.
This fixes no sound on some display devices.
