  RISC-V: Resurrect the MMIO timer implementation for M-mode systems (2020-09-19 13:21:11 -0700)

----------------------------------------------------------------
RISC-V Fixes for 5.9-rc6 (or shortly after)

* A fix for a lockdep issue to avoid an asserting triggering during early boot.
  There shouldn't be any incorrect behavior as the system isn't concurrent at
  the time.
* The addition of a missing fence when installing early fixmap mappings.
* A corretion to the K210 device tree's interrupt map.
* A fix for M-mode timer handling on the K210.

I know it's a it of an odd time, so if these don't make rc6 it's not a big
deal, but I thought I'd just send it out now rather that waiting as these are
ready to go.
