mainboard/amd/gardenia: Remove PMxEE write on S4 resume
Delete the write to PM register 0xee. This register is not
listed in the current BKDG and S4 is not currently supported
on this APU.
NDA document #47517 "A55/.../A85X fusion Controller Hub Register
Reference Guide" provides some clues on the intent of this write.
This register has always been observed to power on with a value
of 0x08 so the write has no effect.
This should be revisited again when SMI and PSP fully implement
the support required for S3.
