Since the driver has been moved to pinctrl and now supports it, move the
documentation into pinctrl folder. In the same time, add documentation
for pinctrl properties such has snps,has-pinctrl and description of pin
alternate functions.

+- snps,has-pinctrl : If present, register the pinctrl controller.
I'm wondering why we can't always assume pin control?
This hardware IP is configured when instantiated to include support for
muxing. If configured without support, the registers will exists but won't
configure anything.
I guess that it's not really a problem but it will lead to unusable
pin muxing.
Can't you determine this by the presence of child nodes?
