Andrey Grodzovsky 64f55e6292 drm/amdgpu: Add RAS EEPROM table. 
Add RAS EEPROM table manager to eanble RAS errors to be stored
upon appearance and retrived on driver load.

v2: Fix some prints.

v3:
Fix checksum calculation.
Make table record and header structs packed to do correct byte value sum.
Fix record crossing EEPROM page boundry.

v4:
Fix byte sum val calculation for record - look at sizeof(record).
Fix some style comments.

v5: Add description to EEPROM_TABLE_RECORD_SIZE and syntax fixes.
