drm/amdgpu: Simplify RAS EEPROM checksum calculations
Rename update_table_header() to
write_table_header() as this function is actually
writing it to EEPROM.
Use kernel types; use u8 to carry around the
checksum, in order to take advantage of arithmetic
modulo 8-bits (256).
Tidy up to 80 columns.
When updating the checksum, just recalculate the
whole thing.
