ARM: dts: imx25: Fix PWM "per" clocks
commit 7ecd0bde5bfea524a843ad8fa8cb66ccbce68779 upstream. Currently PWM functionality is broken on mx25 due to the wrong assignment of the PWM "per" clock. According to Documentation/devicetree/bindings/clock/imx25-clock.txt: pwm_ipg_per 52 ,so update the pwm "per" to use 'pwm_ipg_per' instead of 'per10' clock. With this change PWM can work fine on mx25.
