From: Padmavathi Venna <padm...@samsung.com>
Use generic api to get the pwm clock frequency
Test with command "sf probe 1:0; time sf read 40008000 0 1000".
Try with different numbers of bytes and see that sane values are obtained
Build and boot U-boot with this patch, backlight works properly.

Changes since v2:
- Replaced "exynos5_get_pwm_clk" with "clock_get_periph_rate" in
get_pwm_clk
instead of replacing everywhere.
- Added "Acked-by: Simon Glass".
Changes since v1:
- Restored get_pwm_clk call in case of non-exynos5 cpu.
