Introduce ras counters interface for counting QAT specific device
errors and expose them through the newly created qat_ras sysfs
group attribute.
This adds the following attributes:
- errors_correctable: number of correctable errors
- errors_nonfatal: number of uncorrectable non fatal errors
- errors_fatal: number of uncorrectable fatal errors
- reset_error_counters: resets all counters
These counters are initialized during device bring up and cleared
during device shutdown and are applicable only to QAT GEN4 devices.
