Some usages of ARCH_MX25 are assuming that if it is
defined the other SoCs are undefined. Use SOC_IMX25 for the save
places.

This way FB_IMX can just depend on HAVE_FB_IMX and machines
just need to select IMX_HAVE_PLATFORM_IMX_FB without bothering
about HAVE_FB_IMX.

The mxc-keypad device seems to be the result of an early and partial
merge of the keypad driver. It's unused and there is no corresponding
driver available, so just remove it.

To use common macros to define the gpio ports for imx{1,21,25,27} the
existing ones had to made more general and a few more base address defines
were necessary.

Group soc specific data in a global struct instead of repeating it for each
call to imxXX_add_flexcanX. The structs holding the actual data are placed
in .init.constdata and so don't do much harm. Compared to the previous
approach this reduces code size to call imx_add_flexcan.

Now only the virtual addresses [0xf4000000, 0xf5ffffff] are used for

This makes it more assembler friendly and allows it to be used in situation
that need an unsigned long and not a pointer. Also the naming is
clearer. IOMEM is introduced without IMX_ prefix as it is used this way
in more than one ARM subarch and it might become globally available
soon.

Add function definition for irq_chip.set_wake to enable GPIO to
wake-up the system.
This patch has been tested on a MX51 Babbage system that had suspend
code implemented. The set_wake implementation is necessary for a
GPIO to wake up a system from suspend.

Commit c074512 (imx-esdhc: update devices registration) renamed
MX35_INT_MMC_SDHC2 to MX35_INT_ESDHC2 which broke expansion of the
MXC_INT_MMC_SDHC2 macro.
As (the only user of MXC_INT_MMC_SDHC2) is only used on
mx31 use the MX31 prefixed symbol to define its resources. Moreover to
reduce further confusion mxcsdhc_device0 is fixed accordingly and the MXC
prefixed symbols are removed.

All file_operations should get a .llseek operation so we can make
nonseekable_open the default for future file operations without a
.llseek pointer.
The three cases that we can automatically detect are no_llseek, seq_lseek
and default_llseek. For cases where we can we can automatically prove that
the file offset is always ignored, we use noop_llseek, which maintains
the current behavior of not returning an error from a seek.
New drivers should normally not use noop_llseek but instead use no_llseek
and call nonseekable_open at open time. Existing drivers can be converted
to do the same when the maintainer knows for certain that no user code
relies on calling seek on the device file.
The generated code is often incorrectly indented and right now contains
comments that clarify for each added line why a specific variant was
chosen. In the version that gets submitted upstream, the comments will
be gone and I will manually fix the indentation, because there does not
seem to be a way to do that using coccinelle.
Some amount of new code is currently sitting in linux-next that should get
the same modifications, which I will do at the end of the merge window.
Many thanks to Julia Lawall for helping me learn to write a semantic
patch that does all this.

Rather than checking the MMU status in every instance of addruart, do it
once in kernel/debug.S, and change the existing addruart macros to
return both physical and virtual addresses. The main debug code can then
select the appropriate address to use.
This will also allow us to retreive the address of a uart for the MMU
state that we're not current in.
