There are two equivalent sets of constants for PE states, defined
in arch/powerpc/include/asm/eeh.h and include/uapi/linux/vfio.h.
The former is used by EEH core and the latter is used by userspace.
The patch moves those constants from arch/powerpc/include/asm/eeh.h
to arch/powerpc/include/uapi/asm/eeh.h to avoid maintaining two
equivalent sets of constants.
