refactor(context-mgmt): remove el1_context routines from RMM
This is an effort to optimise the unused members in the cpu_context_t
structure. TF-A statically allocates memory for context entry for
each wolrd per PE. Some of the members in this struct are not used
for all the build combinations.
RMM in particular, is not using this context member and henceforth
removing them.
