RISC-V Patches for 4.0-rc0, Part 2

This patch set contains three major sources of bug fixes:

* Jim has added support for GDB XML files, as well as fixing access to
  CSRs via the GDB stub.
* Alistair has rebased a large set of fixes from Michael that were still
  in his patch queue.  These fix bugs all over our tree, including:
    * Logging of PMP errors.
    * User ABI cleanups and fixes, most notably on RVE guests.
    * Fixes for interrupt emulation fidelity.
    * Improvements to the emulation fidelity of the sifive_u machine.
* Bin Meng has improved the emulation fidelity of the SiFive UART, which
  now supports both TX and RX interrupts (as well as setting the correct
  interrupt line).

This should clear out the bug fix queue that piled up after the
decodetree conversion.
