ARM: 6949/2: mach-u300: fix compilaton warning in IO accessors

Browse Source 
The IO accessors for U300 were using u32 rather than the nominal
void __iomem * type, rectify this by properly defining the
virtual base for statically mapped peripherals to be
void __iomem *. Requires fixing a field in struct clk as well.
