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.
