This series of patches adds support for extended physical address on newer
AMD processors such as AMD 'Milan'. It also, suggests to cache
MCA_CONFIG[McaX] similar to MCA_CONFIG[McaLsbInStatusSupported] to avoid
reading MCA_CONFIG register each time.

The first patch defines a separate helper function to extract
MCA_ADDR[ErrorAddr].

The second patch adds support for extended ErrorAddr bits in MCA_ADDR.

Third patch, caches MCA_CONFIG[McaX] similar to
MCA_CONFIG[McaLsbInStatusSupported] in the existing mce_bank struct.

Last patch, fixes unnecessary padding in mce_bank struct.
