RISC-V Patches for the 4.2 Soft Freeze, Part 2

This patch set contains a handful of small fixes for RISC-V targets that
I'd like to target for the 4.2 soft freeze.  They include:

* A fix to allow the debugger to access the state of all privilege
  modes, as opposed to just the currently executing one.
* A pair of cleanups to implement cpu_do_transaction_failed.
* Fixes to the device tree.
* The addition of various memory regions to make the sifive_u machine
  more closely match the HiFive Unleashed board.
* Fixes to our GDB interface to allow CSRs to be accessed.
* A fix to a memory leak pointed out by coverity.
* A fix that prevents PMP checks from firing incorrectly.

This passes "make chcek" and boots Open Embedded for me.
