This is the third round of patches for mach-lpc32xx, for v3.6. This time,
patches from Alexandre, for PWM support and CPU ID.
If no objections surface, I'll provide pull requests for arm-soc branches
shortly.

LPC32xx SoC has a 128 bits unique id that can be used as a system
serial number, if none has been provided by atags or dt.

Sorry, grabbed old version of patch. Should have been:
pwm: pwm@4005C000 {
compatible = "nxp,lpc3220-pwm";
reg = <0x4005C000 0x8>;
status = "disabled";
};
... because the driver now always registers the two channels together.
Will push it this way.
