I'm surprised that there are not more that need this. Is HAVE_CLK not
enough?

Also HAS_IOMEM is a typical requirement, but I tested with an ARCH=um
config (which does't have HAS_IOMEM) and they all compile fine.

I'm surprised that OF isn't required for PWM_MXS but is is for
PWM_OMAP_DMTIMER. pwm-mxs compiles without CONFIG_OF, didn't test
pwm-omap-dmtimer.
