Ryan Mallon 6618c3ada0 ARM: 6930/1: SPEAr3xx: Rework pmx_dev code to remove conflicts 
Prefix the pmx_devs to remove naming conflicts between the three
SPEAr3xx platforms. Also make pmx_driver static to each platform and
rework the init code to pass the devices rather than export the
pmx_driver structure.
