Use CONFIG_MX6 when the particular processor
variant isn't important.
Reserve the use of CONFIG_MX6Q to
specifically test for quad cores variant.

gpio_get_value() should use PSR like Linux, not DR, because DR does not always
reflect the pin state, while PSR does. This is especially useful to detect a
short circuit on a GPIO pin configured as output, or to read the level of a pin
controlled by a non-GPIO IOMUX function.

Return gpio_set_value in gpio_direction_output.
Earlier it returned 0 and ignored gpio_set_value's return value.

ARM boards should use the generic GPIO API
This means changing gpio to unsigned type
Remove the unused gpio_toggle() function which is not part of the API
Comment that free should not modify pin state

IMX processors has a slightly different interface
to access GPIOs and do not make use of the provided GPIO
framework. The patch substitutes mxc_ specific
functions and make use of the API in asm/gpio.h

As exception among the i.MX processors, the i.MX31 has headers
without general names (mx31-regs.h, mx31.h instead of imx-regs.h and
clock.h). This requires several nasty #ifdef in the drivers to
include the correct header. The patch cleans up the driver and
renames the header files as for the other i.MX processors.

This patch add mxc_gpio support for Freescale MX53 processor

The patch adds support for setting gpios to the
MX51 processor and change name to the corresponding
functions for MX31. In this way, it is possible to get rid
of nasty #ifdef switches related to the processor type.
