Merge remote-tracking branch 'remotes/alistair/tags/pull-riscv-to-apply-20200702-1' into staging

This PR contains two patches to improve PLIC support in QEMU.

It also contains one patch that fixes CLINT accesses for RISC-V. This
fixes a regression for most RISC-V boards.

The rest of the PR is adding support for the v0.7.1 RISC-V vector
extensions. This is experimental support as the vector extensions are
still in a draft state.

This is a v2 pull request that has fixed the building on big endian
machines failure.
