[PATCH] powerpc: mtmsrd not defined

[Sean MacLennan <smaclennan@pikatech.com>]

Let's try a patch to get the ball rolling. 

ldstfp.S does not compile if mtmsrd not defined. But is it only defined
for BOOK3S_64. This defines mtmsrd to be mtmsr on all but BOOK3S_64.
This solves the compile problem... but I am not sure how to test it.

I am also not sure if this is the best place to define it. If the
mapping of mtmsrd to mtmsr is correct, maybe it should be in asm/reg.h?
