x86/mce: Recognise machine check bank signature for data path error
Action required data path signature is defined in table 15-19 of SDM:
+-----------------------------------------------------------------------------+
| SRAR Error | Valid | OVER | UC | EN | MISCV | ADDRV | PCC | S | AR | MCACOD |
| Data Load | 1 | 0 | 1 | 1 | 1 | 1 | 0 | 1 | 1 | 0x134 |
+-----------------------------------------------------------------------------+
Recognise this, and pass MCE_AR_SEVERITY code back to do_machine_check() if
we have the action handler configured (CONFIG_MEMORY_FAILURE=y)
