linux-yocto/3.14: fix common clock framework support in PCI glue layer

The initial version of "spi/pxa2xx: Add common clock framework support in PCI glue layer"
enables the baytrail series of processors, but breaks some existing users of
the framework.

There's a new version of the patch out for review, so we revert the broken one and
udpate to the latest.
