Michal Simek 8b110d157c microblaze: Optimize SAVE_STATE macro
It is necessary to setup BIP and EE and clear EIP
only for unaligned exception handler. The rest of
hw exception handlers don't require it.
HW exception occured and we are not in virtual mode.
That's why we can do operations protected by EIP.
Interrupt, next hw exception or syscall can't occur.

EIP is cleared by rted.

This change speedup page_fault hw exception handler
which is critical path.

There is also necessary to save R11 content before
flag setup for unaligned exception.
