Make AMD SMM SMP aware
Move the SMM MSR init to a code run per CPU. Introduce global SMM_BASE define,
later all 0xa0000 could be changed to use it. Remove the unnecessary test if
the smm_init routine is called once (it is called by BSP only) and also remove
if lock bit is set becuase this bit is cleared by INIT it seems.
Add the defines for fam10h and famfh to respective files, we do not have any
shared AMD MSR header file.
Tested on M2V-MX SE with dualcore CPU.
