pwm: pwm-mxs: encode soc name in compatible string 

Encode soc name in the compatible string to know the specific version
hardware block.  This is the general approach adopted for most bindings.
Change mxs-pwm binding to use the approach.

Freescale MXS PWM controller
Required properties:
- compatible: should be "fsl,mxs-pwm"
- compatible: should be "fsl,imx23-pwm"
- reg: physical base address and length of the controller's registers
- #pwm-cells: should be 2. The first cell specifies the per-chip index
of the PWM to use and the second cell is the duty cycle in nanoseconds.
