qualcomm/sc7180: Cleanups for drivers with common clock

As we move to use the common clock driver, the sc7180 clock driver,
watchdog and display drivers requires few cleanups, thus update the
impacted drivers.

Earlier the display client is expected to provide 2n divider value,
as the divider value in register is in form "2n-1".
mdss_clk_cfg.div = half_divider ? (half_divider - 1) : 0;

The older convention in the upcoming patches would be replaced with the
common macro of QCOM_CLOCK_DIV, thus need the divider needs to be updated.
mdss_clk_cfg.div = half_divider ? QCOM_CLOCK_DIV(half_divider) : 0;

To accommodate impacting the functionality, the half_divider is taken
care in the clock driver.
