The PCIe reset gpio DT fix[1] is in v5.0-rc2. This fix has no effect
without the PCIe driver reset handling patch[2] in v5.0-rc1. But the
combination of both actually breaks PCIe on the Macchiatobin. So I sent
a revert[3].

I tested these patches with U-Boot only. Not sure how EDK handles the
Macchiatobin PCIe serdes initialization and reset GPIO.
