ATJ213x: minor changes to hwstub port
1) Make use of $gp addressing. This saves some bin size and makes
code slightly faster.
2) Substitute jr with simple j instruction in exception handling.
Code is small and j can easily encode target address.
3) Remove nop after eret in interrupt handler. According to mips32r2
ISA manual eret does not have branch delay slot.
