Leandro Lupori 6174048251 powerpc64: Add a trap stack area 
Currently, the trap code switches to the the temporary stack in the dbtrap
section. It works in most cases, but in the beginning of the execution, the
temp stack is being used, as starting in the powerpc_init() code.

In this current scenario, the stack is being overwritten, which causes the
return of breakpoint() to take abnormal execution.

This current patchset create a small stack to use by the dbtrap: codepath
avoiding the corruption of the temporary stack.
