x86 mca: Support MCA recovery actions for latest Intel platforms

When an UC = 1 PCC = 0 MCE happens, there're more types of software
recoverable error defined on on latest Intel Platform. For identifying
those new errors, some new bit (S/AR bit) is defined in MCi_STATUS
register. Also we need MCACOD help's to judge the detailed
error. Combined with the OVER bit, different recovery policies are
required for containing those new errors.

SRAO error  is an software recoverable MCA error, no recovery action
required. while SRAR  is an software recoverable MCA error, recovery
action is required.
