While comments introduced with the original commit claim that
pmuv3_disable_el3()/pmuv3_init_el3() are compatible with PMUv2 and
PMUv1, this is not true in practice: The function accesses the Secure
Debug Control Register (SDCR), which only available to ARMv8 CPUs.
ARMv8 CPUs executing in AArch32 mode would thus be able to disable
their PMUv3, while ARMv7 CPUs would hang trying to access the SDCR.
Fix this by only doing PMUv3 handling when we know a PMUv3 to be
available. This resolves boot hanging on all STM32MP15 platforms
that use SP_min as BL32 instead of OP-TEE.
