crypto: qat - add infrastructure for error reporting

Browse Source 
Add infrastructure for enabling, disabling and reporting errors in the QAT
driver. This adds a new structure, adf_ras_ops, to adf_hw_device_data that
contains the following methods:
  - enable_ras_errors(): allows to enable RAS errors at device
    initialization.
  - disable_ras_errors(): allows to disable RAS errors at device shutdown.
  - handle_interrupt(): allows to detect if there is an error and report if
    a reset is required. This is executed immediately after the error is
    reported, in the context of an ISR.

An initial, empty, implementation of the methods above is provided
for QAT GEN4.
