Manish Pandey 46cc41d559 fix(ras): restrict RAS support for NS world
Current RAS framework in TF-A only supports handling errors originating
from NS world but the HANDLE_EA_EL3_FIRST flag configures it for all
lower Els. To make the current design of RAS explicit, rename this macro
to HANDLE_EA_EL3_FIRST_NS and set EA bit in scr_el3 only when
switching to NS world.

Note: I am unaware of any platform which traps errors originating in
Secure world to EL3, if there is any such platform then it need to
be explicitly implemented in TF-A
