variable as its first parameter, better to pass
a u64 variable as first parameter when calling
do_div function.

EPIT provides another timer implementation besides the default GPT
timer. The imx35 clock driver will use EPIT timer when option
CONFIG_MXC_USE_EPIT is enabled. However, initializing timers from
clock driver is a workaround solution and causes problem when we move
clock drivers into driver/clk.
Let's simply drop the EPIT initialization from there. If people really
want this EPIT option, EPIT timer driver needs to be reworked to do the
initialization in a standard way - use CLOCKSOURCE_OF_DECLARE() with
device tree support.

The usb-clk on sun8i a23 and a33 SoCs is similar to the ones found
on sun6i-a31 SoCs but instead of a 3th phy the a23 / a33 have a hsic
interface which gets enabled by almost the same bits as used on
the a31 for the 3rd phy, but not exactly the same bits so we need
a new compatible for this.
