microblaze: Fix msr instruction detection

Browse source 
Fix msr instructions detection. The current code
just use msrclr for loading msr content and compare
it with proper MSR content. If msrclr is not implemented
r8 contains pc address.
Previous code wanted to use MSR carry bit but if msrclr
wasn't implemented carry wasn't cleared.
