pinctrl: support pinconfig on the U300
This adds pin configuration support for the U300 driver pair,
we can now read out the biasing and drive mode in debugfs and
configure it using the new configuration API.
ChangeLog v1->v2:
- Migrate to pin config and generic pin config changes.
ChangeLog v2->v3:
- Adjust to generic pin config changes in v7 patch set.

pinctrl/coh901: use generic pinconf enums and parameters
Adjust the COH 901 driver to use the standard enums for
biasing and driving pins, alter signature of config function
to suit the framework.

pinctrl: spawn U300 pinctrl from the COH901 GPIO
This solves the riddle on how the U300 pin controller shall be
able to reference the struct gpio_chip even though these are
two separate drivers: spawn the pinctrl child from the GPIO
driver and pass in the struct gpio_chip as platform data.
In the process we rename the U300 "pinmux-u300" to
"pinctrl-u300" so as not to confuse.

pinctrl: move generic functions to the pinctrl_ namespace
Since we want to use the former pinmux handles and mapping tables for
generic control involving both muxing and configuration we begin
refactoring by renaming them from pinmux_* to pinctrl_*.
ChangeLog v1->v2:
- Also rename the PINMUX_* macros in machine.h to PIN_ as indicated
in the documentation so as to reflect the generic nature of these
mapping entries from now on.

pinctrl: break out a pinctrl consumer header
This breaks out a <linux/pinctrl/consumer.h> header to be used by
all pinmux and pinconfig alike, so drivers needing services from
pinctrl does not need to include different headers. This is similar
to the approach taken by the regulator API.

pinctrl/coh901: driver to request its pins
This makes the COH 901 driver request muxing of its GPIO pins
from the pinmux-u300 driver using the standard API calls.

pinctrl: move the U300 GPIO driver to pinctrl
This driver will be converted to a dual GPIO + pinctrl driver
since it supports biasing and driving control options. Hopefully
it can serve as an example.
