Michael Eager 164224e96c Fix for remote G Packet message too long error for baremetal.
Prior to version MicroBlaze v8.10.a,EDK 13.1, XMD's gdbserver stub returned 57
registers in response to GDB's G request. Starting with version MicroBlaze
v8.10.a, EDK 13.1, XMD added the slr and shr register, for a count of 59
registers. This patch adds these registers to the expected G response. This patch
fixes the above problem for baremetal and also supports the backward compatibility.

ChangeLog:
