microblaze: Simplify _debug_exception function

Keep together all arguments for send_sig function.
Move returning address to delay slot which is executed.
Remove additional send_sig loading. I am using IMM part of
rtbd instruction with r0.

old solution:
addik r11, r0, send_sig
rtbd r11, 0
nop

new solution:
rtbd r0, send_sig
nop

There is one instruction saving.
