target-arm: Handle SMC/HVC undef-if-no-ELx in pre_* helpers
SMC must UNDEF if EL3 is not implemented; similarly HVC UNDEFs
if EL2 is not implemented. Move the handling of this from
translate-a64.c into the pre_smc and pre_hvc helper functions.
This is necessary because use of these instructions for PSCI
takes precedence over this UNDEF case, and we can't tell if
this is a PSCI call until runtime.
