Pull spi fixes from Mark Brown:
 "A few driver specific fixes here:

   - SH HSPI was dealing with its clocks incorrectly which meant it
     didn't work on some SoCs, fixing this also requires a small fix to
     one of the SoC clock trees to avoid breaking existing users.
   - The SiRF driver appears to have had several quality problems, it's
     fairly new and not widely used so this isn't too worrying.
   - A brute force fix for excessive locking in the Atmel driver, it
     needs further investigation but this deals with the immediate
     issue.
   - A build fix for the Blackfin driver"
