v4 --> v5 : handle all typo "drvier/driver" in funtion name.

v3 --> v4 : use pcim* function instead of pci* function.
handle typo "drvier/driver" in funtion name.

v2 --> v3 : handle a uninitialized variable in some path.

v2 --> v1 : arch=sh don't support pci, adjust CONFIG_PCI macro.

v1 : QEMU community requires additional PCI devices to simulate PVPANIC devices
so that some architectures can not occupy precious less than 4G of memory
space.
