[Patch, microblaze]: 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
    fixes the above problem for baremetal and also supports the backward compatibility.
