fix(bl32): always include arm_arch_svc in SP_MIN
The PSCI_FEATURES call implementation in TF-A always indicates support
for SMCCC_VERSION, but only BL31 ensures that the corresponding Arm
Architecture Service (arm_arch_svc) is really included in the build.
For SP_MIN only stm32mp1 currently includes it in the platform-specific
make file.
This means that it is easily possible to build configurations that
violate the PSCI/SMCCC specification. On Linux this leads to incorrect
detection of the SMC Calling Convention when using SP_MIN:
[ 0.000000] psci: SMC Calling Convention v65535.65535
Fix this by always including the Arm Architecture Service in SP_MIN
builds. This allows Linux to detect the convention correctly:
[ 0.000000] psci: SMC Calling Convention v1.4
