fix(qemu): fix build error with spmd

Currently when building with PLAT=qemu SPD=spmd SPMC_AT_EL3=1
SPMD_SPM_AT_SEL2=0, there is a build error since
plat_spmd_handle_group0_interrupt() is called irrespective of
SPMC_AT_EL3. Fix this by making plat_spmd_handle_group0_interrupt()
available if SPD_spmd is defined only.
