RISC-V patches for v5.2-rc6

This tag contains fixes, defconfig, and DT data changes for the v5.2-rc
series.  The fixes are relatively straightforward:

- Addition of a TLB fence in the vmalloc_fault path, so the CPU doesn't
  enter an infinite page fault loop;
- Readdition of the pm_power_off export, so device drivers that
  reassign it can now be built as modules;
- A udelay() fix for RV32, fixing a miscomputation of the delay time;
- Removal of deprecated smp_mb__*() barriers.

The tag also adds initial DT data infrastructure for arch/riscv, along
with initial data for the SiFive FU540-C000 SoC and the corresponding
HiFive Unleashed board.

We also update the RV64 defconfig to include some core drivers for the
FU540 in the build.
