This reverts commit c7e0c8535d73f8c5bf760926a2bd71c9840cf2ef, reversing
changes made to dfee09c8acf18e84fe197bb5d821d1e4e02d020f.
John Stultz reports that Panda doesn't boot anymore and 'git bisect'
indicated the merge commit itself as the culprit. The resulting kernel
log is:

Revert it so a later version of the arm-soc merge result can be used
instead.

There are several occurences where MXC_INTERNAL_IRQ is
assumed to be the start of the gpio interrupts. It was never
meant this way. Replace these with gpio_to_irq.

The patch makes necessary changes on gpio-mxc as below to turn it
into an upstanding gpio driver.
* Add a list to save all mx2 ports references, so that
mx2_gpio_irq_handler can walk through all interrupt status
registers
* Use readl/writel to replace mach-specific accessors
__raw_readl/__raw_writel
* Change mxc_gpio_init into mxc_gpio_probe function
* Move "struct mxc_gpio_port" into gpio-mxc.c, as it needs not to
be public at all, and also make some other cleanup on
plat-mxc/include/mach/gpio.h at the same time
And the patch then migrates mach-imx and mach-mx5 to the updated
driver by adding corresponding platform devices.

mxc_board_init is too generic to be useful. Additionally change some
mxc_timer to ${machine}_timer, too.

This used to be done in .map_io which is supposed to only setup the
memory mapping.

Add support for dynamical allocation of imx-keypad on mx5 platform.
After moving to dynamically registration of the keypad, the keypad clock
name needs to change accordingly.
The reason is that the original mx5 keypad platform_device id was 0,
now we use id=-1 as per arch/arm/plat-mxc/devices/platform-imx-keypad.c.
Tested keypad successfully on a MX51_3DS board.

This iomux file has been constructed from the Freescale pinmux tool.
It contains all pins from the tool, but the datasheet lists some
configurations not present in the tool, these are not yet added.

PHYS_OFFSET may become a variable once the runtime PHYS_OFFSET
patch is merged, so use MX51_PHYS_OFFSET for boot_params.

The following patch is a first step to convert the 'struct pad_desc'
to a bitmapped cookie to facilitate adding platform specific pullup or
drive strength definitions to existing pad definitions without need to
rewrite the complete pad def.
The patch wraps 'struct pad_desc' in an opaque data type and
introduces macros to access the individual members.
This patch does not constitute any functional change!

Since we're now using addruart to establish the debug mapping, we can
remove the io_pg_offst and phys_io members of struct machine_desc.
The various declarations were removed using the following script:
grep -rl MACHINE_START arch/arm | xargs \
sed -i '/MACHINE_START/,/MACHINE_END/ { /\.\(phys_io\|io_pg_offst\)/d }'
[ Initial patch was from Jeremy Kerr, example script from Russell King ]
