mb/intel/adlrvp{p,m}: Enable dynamic GPIO PM
GPIO PM was disabled for adlrvp to evaluate if longer interrupt pulses
are required for ADL. Since ADL requires 4us long pulses (EDS:626817),
GPIO PM can be enabled. This change drops the GPIO PM override and
re-enables dynamic GPIO PM.
TEST=Boot adlrvp to OS, ensure no TPM timeout errors.
