Allow pwm_enable()/pwm_disable() to be called as many times

The PWM model is different from things like the clock API
where we need enable counting, because PWMs have one

284d115ec9 [ARM] pxa: separate PXA25x and PXA27x UDC register definitions
The PXA25x and PXA27x USB device controller register definitions are
different.  Currently, they live side by side in pxa-regs.h, but only
one set is available depending on the setting of PXA25x or PXA27x.

This means that if we build to support both PXA25x and PXA27x, the
PXA27x definitions are unavailable, even to PXA27x specific code.

Remove these definitions from pxa-regs.h, and place them in separate
files.  Include these files where appropriate.

Note: according to the dependencies in drivers/usb/gadget/Kconfig,
we do not support the UDC on PXA27x nor PXA3xx CPUs, so remove the
platform devices from pxa27x.c and pxa3xx.c.

Related to d3930614e6.

RCSR is only present on PXA2xx CPUs, not on PXA3xx CPUs.  Therefore,
we should not be unconditionally writing to RCSR from generic code.

Since we now clear the RCSR status from the SoC specific PXA PM code
and before reset in the arch_reset() function, the duplication in
the corgi, poodle, spitz and tosa code can be removed.
