Prabhakar Kushwaha 689f00fc7e powerpc/85xx:Make debug exception vector accessible
Debugging of e500 and e500v1 processer requires debug exception vecter (IVPR +
IVOR15) to have valid and fetchable OP code.

1) While executing in translated space (AS=1), whenever a debug exception is
generated, the MSR[DS/IS] gets cleared i.e. AS=0 and the processor tries to
fetch an instruction from the debug exception vector (IVPR + IVOR15); since now
we are in AS=0, the application needs to ensure the proper TLB configuration to
have (IVOR + IVOR15) accessible from AS=0 also.
Create a temporary TLB in AS0 to make sure debug exception verctor is
accessible on debug exception.

2) Just after relocation in DDR, Make sure IVPR + IVOR15 points to valid opcode
