RTCM will sit in OS boot media instead of IFWI image
So update SBL logic to load RTCM from OS boot media.
If the RTCM could not be found, SBL should continue
boot normal OS.

SBL allows extra module to be called before tranfering into the main
boot option. For example, RTCM module can be called for boot option
with TCC feature support. This patch enabled this support. Since the
extra module might have different ARCH mode from current SBL mode,
thunk will be provided if mismatching is detected.
