The function at91_dt_node_to_map is ultimately called by the function
pinctrl_get, which is an exported function.  Since it is possible that this
function is not called from within a probe function, for safety, the kfree
is converted to a devm_kfree, to both free the data and remove it from the
device in a failure situation.

Marvell's PXA/MMP silicon also match the behavior of pinctrl-single.
Each pin binds to one register. A lot of pins could be configured
as gpio.

GPIO range is defined as a child node of pinmux in .dtsi file. If those
pins are with the same gpio function configuration in the pinmux
register, they could be defined in the same GPIO range. For this new
child node, two properties are used.

reg = <the start of pinmux register in range, size of range>

pinctrl-single,gpio: <gpio base in range, the gpio function of the range
		in the pinmux register>

Let's stop spawning the pinctrl driver from the GPIO driver,
we have these two mechanisms broken apart now, and they can
each probe in isolation. If the GPIO driver cannot find its
pin controller (pinctrl-u300), the pin controller core will
tell it to defer probing.

Instead of having the pinctrl driver register the GPIO range
for the gpio_chip, making it necessary to instantiate the
pin controller from the GPIO driver and pass the GPIO chip as
platform data, now let the GPIO chip driver register it's own
ranges and have the pinctrl driver look up the GPIO chip from
the pinctrl core as necessary.

This adds a function to the pinctrl core to retrieve the GPIO
range associated with a certain pin for a certain controller.
This is needed when a pinctrl driver want to look up the
corresponding struct gpio_chip for a certain pin. As the
GPIO drivers can now create these ranges themselves, the
pinctrl driver no longer knows about all its associated GPIO
chips.
