Mario Limonciello 6bc3462a0f pinctrl: amd: Mask wake bits on probe again 
Shubhra reports that their laptop is heating up over s2idle. Even though
it's getting into the deepest state, it appears to be having spurious
wakeup events.

While debugging a tangential issue with the RTC Carsten reports that recent
6.1.y based kernel face a similar problem.

Looking at acpidump and GPIO register comparisons these spurious wakeup
events are from the GPIO associated with the I2C touchpad on both laptops
and occur even when the touchpad is not marked as a wake source by the
kernel.

This means that the boot firmware has programmed these bits and because
Linux didn't touch them lead to spurious wakeup events from that GPIO.

To fix this issue, restore most of the code that previously would clear all
the bits associated with wakeup sources. This will allow the kernel to only
program the wake up sources that are necessary.

This is similar to what was done previously; but only the wake bits are
cleared by default instead of interrupts and wake bits.  If any other
problems are reported then it may make sense to clear interrupts again too.
