fix(intel): fix ECC Double Bit Error handling

SError and Abort are handled in Linux (EL1) instead of
EL3. This patch adds some functionality that complements the
use cases by Linux as follows:

- Provide SMC for ECC DBE notification to EL3
- Determine type of reset needed and service the request in
  place of Linux
