Regression: hang on BYT with new pstate support

[Jesse Barnes]

The drm-intel tree just updated to 3.13-rc, and I started seeing early
hard hangs on my BYT system.  I bisected it down to this commit:

commit 19e77c28dbf1972305da0dfeb92a62f83df3a91d

    intel_pstate: Add Baytrail support
    
    Add support for the Baytrail processor.

The hangs occur at different times, so unless the get/set functions
aren't called until we change the state, the problem may be in the
core_set_pstate function instead?  Maybe it's not suited to BYT somehow?

Thanks,
