During the hibernate entry sequence, ACP registers will be reset to
default values and acp ip will be completely powered off including acp
SoundWire pads. During resume sequence, if acp SoundWire pad keeper enable
register is not restored along with pad pulldown control register value,
then SoundWire manager links won't be powered on correctly results in
peripheral register access failures and completely audio function is
broken.
Add code to store the acp SoundWire pad keeper enable register and acp pad
pulldown ctrl register values before entering into suspend state and
restore the register values during resume sequence based on condition check
for acp SoundWire pad keeper enable register for ACP6.3, ACP7.0 & ACP7.1
platforms.
