soc/intel/common/block/pcie/rtd3: Skip Power On if _STA returns 1
RTD3,_ON method sometimes can create delays during system boot.
Even when the power is already up, kernel still tries to call _ON
method to power up device, but it's unnecessary.
RTD3._STA returns device power, so _ON method can check _STA and see
if the power on process can be skipped
BUG=b:249931687
TEST=system can boot to OS with RTD3 pcie storage and save ~80 ms on
Crota. Suspend stress test passes 100 cycles
