pinctrl-pxa driver doesn't support well on DT mode. Now pinctrl-single
could support DT mode & pin configuration. Use pinctrl-single driver to
support MMP/PXA silicons instead.

The pinconf, pinctrl and pinmux operation structures hold function
pointers that are never modified. Declare them as const.

Convert all uses of devm_request_and_ioremap() to the newly introduced
devm_ioremap_resource() which provides more consistent error handling.
devm_ioremap_resource() provides its own error messages so all explicit
error messages can be removed from the failure code paths.

Use managed resources API to simplify the code.
Also ensure we do request mem_region before ioremap.

Most of the SoC drivers implement list_groups() and list_functions()
routines for pinctrl and pinmux. These routines continue returning
zero until the selector argument is greater than total count of
available groups or functions.
This patch replaces these list_*() routines with get_*_count()
routines, which returns the number of available selection for SoC
driver. pinctrl layer will use this value to check the range it can
choose.
This patch fixes all user drivers for this change. There are other
routines in user drivers, which have checks to check validity of
selector passed to them. It is also no more required and hence
removed.
Documentation updated as well.
