mb/google/skyrim: use gpio.h include

Replace the amdblocks/gpio.h and soc/gpio.h includes with the common
gpio.h which will include soc/gpio.h which will include amdblocks/gpio.h
in the AMD SoC case.
Since baseboard/ec.h and indirectly baseboard/gpio.h files will get
included in the DSDT, the soc/gpio.h includes in those aren't replaced
with a gpio.h include for now.
