The hypervisor v0.5 spec introduces two new CSRs for both M-mode
and HS-mode which need to be considered when redirecting traps
hence this patch.

We generally don't get misaligned load/store traps from Linux/U-Boot
compiled using GCC 8.2 or higher but this is not true with older
GCC toolchains. To tackle this we add misaligned load/store trap
handling adopted from BBL sources but much more simpler.
(Note: BBL sources can be found at https://github.com/riscv/riscv-pk.git)
