powerpc/of: Remove useless register save/restore when calling OF back enter_prom() used to save and restore registers such as CTR, XER etc.. which are volatile, or SRR0,1... which we don't care about. This removes a bunch of useless code and while at it turns an mtmsrd into an MTMSRD macro which will be useful to Book3E. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
