Clean up the existing export namespace code along the same lines of
commit 33def8498fdd ("treewide: Convert macro and uses of __section(foo)
to __section("foo")") and for the same reason, it is not desired for the
namespace argument to be a macro expansion itself.

With 16 channel pwm support, we're registering two instances of pwm_chip
with 8 channels each. We need to update PM functions to use both instances
of pwm_chip during power state transitions.
Introduce struct dwc_pwm_drvdata and use it as driver_data, which will
maintain both instances of pwm_chip along with dwc_pwm_info and allow us
to use them inside suspend/resume handles.

Intel Elkhart Lake PSE includes two instances of PWM as a single PCI
function with 8 channels each. Add support for the remaining channels.

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.

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.

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.

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.
