Allow mfspr, mtspr with a register number.

PowerPC has a few hundred special-purpose registers.  The assembler
had only accepted the names "xer", "lr", "ctr".  Most programs use
only those three SPRs.  If I add more names, they would almost never
get used, and they might conflict with labels.

I want to use "mfspr r3, 0x3f0" and "mtspr 0x3f0, r3" in
plat/qemu/boot.s to access register hid0 from supervisor mode.
