fix: remove test config with SDEI support enabled for SPD=SPMD

As EL1 and EL2 contexts are now being decoupled, the
above build config, need to be modified.

* When SPD=SPMD, software at SEL2, takes care of handling
  EL1 context. EL3 no longer need to be concerned about
  EL1 context.

* On the other side, SDEI support needs EL1 context to delegate
  interrupts  to the software running at lower Non-secure
  exception levels.

* So taking both into consideration, we need to re-configure the
  original test, which intended at mimicing RAS handling in a
  two world setup. If feasible try and emulate the same with
  EL3 SPMC setup which has a single partiton at S-EL1 or
  refactor original tf-a code to cater for a two world setup
  with SPMC at S-EL1 and a SP at S-EL0

* At this moment, removing this test_config, to get through the
  changes, concerning to decoupling of EL1/EL2 context.
