This commit addresses the issue by disabling the IRQ before unregistering
the TCPCI port in both the remove and shutdown handlers. This ensures that
no new interrupts are handled after the port is unregistered, preventing
potential race conditions or use-after-free issues.

Writing reg 0x300 BIT(31) may cause the DMA module to falsely
trigger writing data. It will case enc err.
So we need to disable the core clock before writing reg 0x300,
and re-enable the core clock after writing reg 0x300.

The parent clock of PCLK_HDPTX_APB is PCLK_PMUPHY_ROOT,
which must be always on.
In order to reduce power consumption, replace apb clock
PCLK_PMUPHY_ROOT by controllable PCLK_HDPTX_APB in
suspending and resuming.

This patch supports select and swap ADC data, the item
'Left Right' is default.
For example, swap left and right for ADC:
----
amixer -c 0 sset 'ADC Data Select' 'Right Left'
Simple mixer control 'ADC Data Select',0
Capabilities: enum
Items: 'Left Right' 'Left Left' 'Right Right' 'Right Left'
Item0: 'Right Left'

Generally speaking, the codec needs to ensure the normal
input of left and right channels independently. If you
want to forcethe duplication of channels, you can configure
it through the control node in the user layer.
Enabling ALC NG here will cause the sound pickup effect
to be unstable.
And, the default public version does not need to turn on
the ALC NG function, so as not to introduce non-linear
processing to the backend algorithm and cause unnecessary
confusion to developers.

ciu clock from CRU is 2 times of interface clock, so the delay number

The husb311 driver disable irq wakeup if vbus is on
(e.g connect with an U Disk), it aimed to avoid wakeup
system from deep sleep immediately by husb311 irq if
the vbus was powered off during deep sleep.
However, some platforms can keep vbus on during deep
sleep, and it may want to support the husb311 irq to
wakeup system from deep sleep, so this patch adds an
option property "wakeup-source" for this scenario.
