42d4d3baac refactor(build): distinguish BL2 as TF-A entry point and BL2 running at EL3
BL2_AT_EL3 is an overloaded macro which has two uses:
	1. When BL2 is entry point into TF-A(no BL1)
	2. When BL2 is running at EL3 exception level
These two scenarios are not exactly same even though first implicitly
means second to be true. To distinguish between these two use cases we
introduce new macros.
BL2_AT_EL3 is renamed to RESET_TO_BL2 to better convey both 1. and 2.
Additional macro BL2_RUNS_AT_EL3 is added to cover all scenarious where
BL2 runs at EL3 (including four world systems).

BREAKING CHANGE: BL2_AT_EL3 renamed to RESET_TO_BL2 across the
repository.

c703d752cc 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

1f1c0206d8 build(intel): define a macro for SIMICS build
SIMICS builds have different UART configurations compared
to hardware build. Hence, this patch defines a macro to
differentiate between both.
