include/cpu/amd/msr: move SMM_LOCK bit right after HWCR_MSR definition
The SMM_LOCK bit isn't in SMM_MASK_MSR, but in HWCR_MSR, so move it
there. The soc/amd/* code itself uses the bit definition when accessing
HWCR_MSR, so SMM_LOCK was just below the wrong MSR definition.
Also remove SMM_LOCK from comment about masking bits in SMM_MASK_MSR,
since that bit isn't in that MSR.
TEST=Checked the code and the corresponding BKDG/PPR.
