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.

TEST=Verify timings between GPIO init sections. All available modules
are present after training.
