In order to use the gpiolib, we now have to call gpio_request in
the plaform code since it is not done in iomux code anymore.

This allows us to have more mapping functions for more than one
i.MX architecture in the kernel. As this is the earliest board
specific hook we have, also use it to set the cpu type.

On MX31 we can't do much without mapping the AIPS1/2 register space.
Move these mappings from individual boards to plat-mxc/mm.c

The i.MX31ADS supports pluggable PMU modules, including the WM835x based
Wolfson Microelectronics 1133-EV1. These boards provide power, audio,
RTC and watchdiog services to the system. This patch adds initial support
for those boards in I2C mode.
Currently support is limited by the available support for the features
of the i.MX31 in the mainline kernel. Some further work will be needed
once other PMU modules are supported and once there is SPI support.
Many of the regulator constraints will be sharable with other PMU
boards.

- rename mxc_clocks_init to architecture specific versions. This
allows us to have more than one architecture compiled in.
- call mxc_timer_init from clock initialisation instead from board

Remove includes of asm/hardware.h in addition to asm/arch/hardware.h.
Then, since asm/hardware.h only exists to include asm/arch/hardware.h,
update everything to directly include asm/arch/hardware.h and remove
asm/hardware.h.

This patch adds timer support for the i.MX machine family. This code can
be used on the following machs:
- i.MX1 (tested)
- i.MX2 (i.MX21 (to be tested), i.MX27 (tested))
- i.MX3 (i.MX31 (tested))
TODO: It seems impossible to build a kernel for more than one CPU because the
timer do not follow the platform device rules. So it does only work if
timer 1 can be accessed on all CPUs at the same address.

This patch adds the foundation pieces for
the Freescale MXC platforms, including
i.MX2 and i.MX3 based systems.
The bare-bones MX31 support in this patch
boots to the rootdev panic with 8250 serial
console configured "console=ttyS0,115200".
It assumes that Redboot is the boot loader.
