e3c9b0ddfd misc: microchip: pci1xxxx: fix dependency issues in building the pci1xxxx's aux bus driver.
build errors and warnings listed below and reported by kernel
test robot <lkp@intel.com> on the char-misc-next branch are
fixed in this add-on patch.

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.
