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 Change-Id: I296ce1b85417a5dbaca558511cd7fc51a3a38c84 Signed-off-by: Kane Chen <kane.chen@intel.corp-partner.google.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/69189 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Eric Lai <eric_lai@quanta.corp-partner.google.com> Reviewed-by: Subrata Banik <subratabanik@google.com>
