Martin Roth 3360862687 mb/google/guybrush: Update romstage power-on timings for PCIe
This configures the romstage portion of the PCIe GPIOs in the correct
sequence to meet the power-on timings.

The PCIe_RST line is anded with the Aux reset lines, so to take the PCIe
devices out of reset, both need to be brought hign.

BUG=b:184796302, b:184598323
TEST=Verify timings between GPIO init sections.  All available modules
are present after training.
