platform/x86/amd: pmc: add CONFIG_SERIO dependency

Using the serio subsystem now requires the code to be reachable:

x86_64-linux-ld: drivers/platform/x86/amd/pmc.o: in function `amd_pmc_suspend_handler':
pmc.c:(.text+0x86c): undefined reference to `serio_bus'

Add the usual dependency: as other users of serio use 'select'
rather than 'depends on', use the same here.
