aarch32: stop speculative execution past exception returns
aarch32 CPUs speculatively execute instructions following a
ERET as if it was not a jump instruction. This could lead to
cache-based side channel vulnerabilities. The software fix is
to place barrier instructions following ERET.
The counterpart patch for aarch64 is merged:

AArch32: Disable Secure Cycle Counter
This patch changes implementation for disabling Secure Cycle
Counter. For ARMv8.5 the counter gets disabled by setting
SDCR.SCCD bit on CPU cold/warm boot. For the earlier
architectures PMCR register is saved/restored on secure
world entry/exit from/to Non-secure state, and cycle counting
gets disabled by setting PMCR.DP bit.
In 'include\aarch32\arch.h' header file new
ARMv8.5-PMU related definitions were added.
