The Arm Architecture Service (arm_arch_svc) is required for SP_MIN on
AArch32 because the PSCI_FEATURES call implementation in TF-A always
indicates support for SMCCC_VERSION. However, currently it cannot be
built for AArch32 because all the workaround check functions
(check_wa_cve_2017_5715(), check_smccc_arch_wa3_applies(), ...)
are not implemented for AArch32.
While this should be ideally fixed at some point, disable the
SMCCC_ARCH_WORKAROUND implementations for AArch32 for now so at least
the rest of the calls can be built correctly. This still helps overall
because implementing SMCCC_VERSION is mandatory while the workaround
calls are optional.
