pinctrl: spear: spear: Convert to regmap

Resources need to be shared between pinmux and plgpio.

Use regmap (syscon) to access resources to allow an
easy way to share resources.

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.

Drivers: pinctrl: remove __dev* attributes.

CONFIG_HOTPLUG is going away as an option. As a result, the __dev*
markings need to be removed.

This change removes the use of __devinit, __devexit_p, __devinitdata,
and __devexit from these drivers.

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

pinctrl: remove use of __devexit

CONFIG_HOTPLUG is going away as an option so __devexit is no

pinctrl: SPEAr: Add SoC specific gpio configuration routines

Different SPEAr SoCs have different approach to configure pins as gpios. Some
configure a group of gpios with single register bit and others have one bit per
gpio pin. Only earlier one is implemented till now, this patch adds support for
later one.

Here we add callbacks to SoC specific code to configure gpios in
gpio_request_enable(). That will do additional SoC specific configuration to
enable gpio pins.

We also implement this callback for SPEAr1340 in this patch.
