Merge remote-tracking branch 'remotes/alistair/tags/pull-riscv-to-apply-20201217-1' into staging

A collection of RISC-V improvements:
 - Improve the sifive_u DTB generation
 - Add QSPI NOR flash to Microchip PFSoC
 - Fix a bug in the Hypervisor HLVX/HLV/HSV instructions
 - Fix some mstatus mask defines
 - Ibex PLIC improvements
 - OpenTitan memory layout update
 - Initial steps towards support for 32-bit CPUs on 64-bit builds
