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

TEST=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.

I don't believe this file is used now.
