pwm: dwc: Make use of devm_pwmchip_alloc() function
This prepares the pwm-dwc driver to further changes of the pwm core
outlined in the commit introducing devm_pwmchip_alloc(). There is no
intended semantical change and the driver should behave as before.
Also convert the to_dwc_pwm() helper macro to a static inline to get
some type safety.

pwm: dwc: Prepare removing pwm_chip from driver data
This prepares the driver for further changes that will drop struct
pwm_chip chip from struct dwc_pwm. Use the pwm_chip as driver
data and return value of dwc_pwm_alloc() instead of the dwc_pwm to get
access to the pwm_chip in dwc_pwm_probe() and dwc_pwm_suspend() without
using dwc->chip.
Thanks to Raag Jadav for providing a hunk of this patch that Uwe missed
during creation of this patch.

pwm: dwc: make timer clock configurable
Add a configurable clock base rate for the pwm as when being built
for non-PCI the block may be sourced from an internal clock.

pwm: dwc: split pci out of core driver
Moving towards adding non-pci support for the driver, move the pci
parts out of the core into their own module. This is partly due to
the module_driver() code only being allowed once in a module and also
to avoid a number of #ifdef if we build a single file in a system
without pci support.
