It moves a bunch of header files included in hardware.h and itself
from mach-imx/include/mach to mach-imx, and updates users to include
hardware.h rather than mach/hardware.h.  The files in mach-imx/devices
will need to include "../hardware.h".

The board files in mach-imx are the only users of iomux drivers and

This fixes the following warning in a mx3_defconfig build:

	arch/arm/mach-mx3/mach-bug.c: In function 'bug_board_init':
	arch/arm/mach-mx3/mach-bug.c:47: warning: passing argument 1 of 'mxc_iomux_setup_multiple_pins' discards qualifiers from pointer target type

While at it remove some useless consts from unsigned int arguments.

This just leaves cpu.c, devices.c and mm.c to clean up.  As these files
are used on more than one SOC they need some more work.

Since iomux code is not directly related to gpio on mx31, the calls
to gpio_request are removed from iomux.c file.

These calls have to be done in platform initialization files. The
name of the singe pin call for iomux is also changed to
mxc_iomux_alloc_pin.

This new implemenatation avoids that two physical pins are claimed by
the same driver (also with the the gpr hardware modes).
The gpio kernel lib is also called when a capable gpio pin is assigned
its gpio function.
The mxc_iomux_mode function is still here for backward compatibility but
should not be used anymore.

V2:

In the precendent revision, the iomux code was claiming a pin when its
hardware mode was changed. This was uncorrect: when the hardware mode is
changed, the pin must still be claimed through the iomux.

In order to have a pin working in mode hw2, we must fist issue the
mxc_iomux_set_gpr call and then the corresponding mxc_iomux_mode calls
with the FUNC mode (usually done with mxc_iomux_setup_multiple_pins).
The reverse calls must be done to fee the pins.

Remove includes of asm/hardware.h in addition to asm/arch/hardware.h.
