The UEFI Specification v2.8, Table 299, Memory Error Record has
several changes from previous versions. Bits 18 through 21 have been
added to the memory validation bits to include an extended version
of row, an option to print bank address and group separately, and chip id.
These patches implement bits 18 through 21 into the Memory Error Record.

Change reserved field to extended field in cper_sec_mem_err structure
and added the extended field to the cper_mem_err_compact structure.

Print correct versions of row, bank, and chip ID.

v1 -> v2:
   * Add static inline cper_get_mem_extension to make
     it more readable, as suggested by Borislav Petkov

   * Add second patch for bank field, bank group, and chip id.
