clk: wrap I/O access for improved portability
the common clock drivers were motivated/initiated by ARM development and apparently assume little endian peripherals wrap register/peripherals access in the common code (div, gate, mux) in preparation of adding COMMON_CLK support for other platforms Signed-off-by: Gerhard Sittig <gsi@denx.de> Signed-off-by: Mike Turquette <mturquette@linaro.org>
