Send WAKEUP event properly in ITE Tech touch driver when device
is in suspend mode.
The driver maintins a boolean state for sending the WAKEUP event.
When user taps the screen for touch-to-wake feature, the irq
handler for ITE Tech touch driver is scheduled after the ITE tech
resume function. Due to this the boolean state gets reset.
So this change handles this use case properly.

When NFC is not enabled, IRQ will be disabled and
then if we do suspend/resume wake up functionality
won't be enabled at suspend but we try to disable
the same at resume and cause irq warning.
Fix warning trace in below cases :
1) NFC enabled in makefile, but manually turned off in
settings menu (NFC driver is enabled and hw is present).
2) NFC is not enabled in makefile
(NFC driver is enabled and hw is present).

state of memory core and periphery control when branch clock is off.
Since mdss does not have retention requirement for axi, both memory core

axi clock is off.
