sm8250-common: Drop PASR properties

* vendor.power.pasr.enabled is unused and vendor.pasr.activemode.enabled
   is only used on property:vendor.pasr.enabled=true, which isn't the
   case since we disable memory hotplugging kernel.

verify_pasr_support()
{
         if [ -d /sys/kernel/mem-offline ]; then
                setprop vendor.pasr.enabled true
         fi
}
