spapr_ovec.c is a device, but it uses target_ulong which is
target specific. The hwaddr type (declared in "exec/hwaddr.h")
better fits hardware addresses.
Change spapr_ovec_parse_vector() to take a hwaddr argument,
allowing the removal of "cpu.h" in a device header.

IIUC, Option vectors represents a data structure of vectors to advertise
guest capabilities to the platform (ref b20b7b7adda4) and doesn't really
represent a hardware device by itself. IMHO, target_ulong appears to be
more appropriate for this purpose. However, the header file inclusion
could be changed to cpu-defs.h if target_ulong is the only requirement here.
