Exynos: Add peripherial id for pwm

Add peripherial id for pwm inorder to support
generic api to get the clk 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.
