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.

+ PWM driver for Synopsys DWC PWM Controller.
Currently pwm-dwc doesn't contain a driver but is only a library used by
pwm-dwc-pci (and later the of driver). As such it doesn't make sense to
be user-selectible, does it?
I suppose the PWM_DWC should select the original driver an a new
PWM_DW_CORE should build the actual core driver.
