ARM: 6949/2: mach-u300: fix compilaton warning in IO accessors
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. Signed-off-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
