RAS: Add helpers to access Standard Error Records
The ARMv8 RAS Extensions introduced Standard Error Records which are a
set of standard registers through which:
- Platform can configure RAS node policy; e.g., notification
mechanism;
- RAS nodes can record and expose error information for error handling
agents.
Standard Error Records can either be accessed via. memory-mapped
or System registers. This patch adds helper functions to access
registers and fields within an error record.
