  riscv: Avoid kgdb.h including gdb_xml.h to solve unused-const-variable warning (2020-07-09 20:12:28 -0700)

RISC-V Fixes for 5.8-rc5 (ideally)

I have a few KGDB-related fixes that I'd like to target for 5.8-rc5.  They're
mostly fixes for build warnings, but there's also:

* Support for the qSupported and qXfer packets, which are necessary to pass
  around GDB XML information which we need for the RISC-V GDB port to fully
  function.
* Users can now select STRICT_KERNEL_RWX instead of forcing it on.

I know it's a bit late for rc5, as these are not critical it's not a big deal
if they don't make it in.
