[PATCH] x86: bug fix in P6 Machine check initialization

Make P6 MCA initialization code complaint with guidelines in IA-32 SDM
Vol3.  Bank 0 control register should not be set by OS and clear status
registers on all banks on reset.

This will prevent false MCE alarms on the systems that has some non-MCE
information left-over in MC0_STATUS on reboot.
