[PATCH 02/20] qemu, lxc: move NodeDeviceGetPCIInfo() function to domain_driver.c

Mon Jan 4 12:54:26 UTC 2021
libxlNodeDeviceGetPCIInfo() and qemuNodeDeviceGetPCIInfo() are equal.
Let's move the logic to a new virDomainDriverNodeDeviceGetPCIInfo()
info to be used by libxl_driver.c and qemu_driver.c.
