Allow pwm_enable()/pwm_disable() to be called as many times
as the driver wants (and not even count them).
The PWM model is different from things like the clock API
where we need enable counting, because PWMs have one
exclusive user per PWM whereas the clock API can have
multiple users of the same clock.

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.

If CONFIG_BACKLIGHT_CORGI is not selected, then corgibl_limit_intensity()

symbol, resulting in a link error.

Wrap the references with the relevant ifdefs, and avoid the resulting
NULL pointer dereference by making the code in sharpsl_pm.c also
conditional on the config symbol.

Patch mainly from Eric Miao, with minor edits by rmk.

Note: PWM0 and PWM2 share the same register I/O space and clock gating
on pxa{27x, 3xx}, thus PWM2 is treated in the driver as a child PWM of
PWM0. And this is also true for PWM1/3.

Related to d3930614.

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.
