fix(spe): drop SPE EL2 context switch code
At the moment we hardcode the SPE functionality to be available on the
non-secure side only, by setting MDCR_EL3.NSPB accordingly.
This also means that the secure world cannot use SPE, so there is no
need to context switch the PMSCR_EL2 register.
Drop the SPE bits from the EL2 context switch code. If any of the other
EL2 worlds wish to start using SPE, this can be brought back.
