pinctrl: nomadik: Add missing header(s)

Do not imply that some of the generic headers may be always included.
Instead, include explicitly what we are direct user of.

While at it, sort headers alphabetically.

pinctrl: ab8505: Define group for GPIO pin 50

The Hulk robot reports an usused varible:

drivers/pinctrl/nomadik/pinctrl-ab8505.c:137:23: warning:
‘gpio50_a_1_pins’ defined but not used [-Wunused-const-variable=]
static const unsigned gpio50_a_1_pins[] = { AB8505_PIN_L4 };
^~~~~~~~~~~~~~~

This variable actually should be used. Probably an oversight
by the driver author.

pinctrl: nomadik: Fix SPDX tags

Some files were missing the appropriate SPDX tags so
fixed it up.

pinctrl: Include <linux/gpio/driver.h> nothing else

These drivers are GPIO drivers, and the do not need to use the
legacy header in <linux/gpio.h>, go directly for
<linux/gpio/driver.h> instead.

Replace any use of GPIOF_* with 0/1, these flags are for
consumers, not drivers.

Get rid of a few gpio_to_irq() users that was littering
around the place, use local callbacks or avoid using it at
all.

pinctrl: nomadik: move all Nomadik drivers to subdir

We have a bunch of Nomadik family pin control drivers, so let's
move them into their own subdirectory.
