c8b4747569 misc: microchip: pci1xxxx: Do not disable the pci device twice in gp_aux_bus_remove() 
gp_aux_bus_probe() uses pcim_enable_device(), so there is no point in
calling pci_disable_device() explicitly in the remove function.

393fc2f594 misc: microchip: pci1xxxx: load auxiliary bus driver for the PIO function in the multi-function endpoint of pci1xxxx device. 
pci1xxxx is a PCIe switch with a multi-function endpoint on one of its
downstream ports. PIO function is one of the functions in the
multi-function endpoint. PIO function combines a GPIO controller and also
an interface to program pci1xxxx's OTP & EEPROM. This auxiliary bus driver
is loaded for the PIO function and separate child devices are enumerated
for GPIO controller and OTP/EEPROM interface.
