This is to fix cpu-abort with 'qemu: fatal: unknown mfs reg d'
(in the default case) when microblaze guest issues 'MFS Rd,EDR'
instruction.
Since embeddedsw release 2019.2, XPlm_ExceptionHandler() issues
the instruction on exception, and microblaze model aborts when
PLM firmware guest encounters an exception.
