To be able to compile e.g. i.MX31 and i.MX51 in a single kernel image
the ioremap quirk needs a runtime check.
While touching this code make the comment more understandable by adding
a sentence from the commit log that introduced it
(eadefef ([ARM] MX3: Use ioremap wrapper to map SoC devices nonshared)).
As mach/io.h now uses cpu_is_ some header reshuffling in mach/hardware.h
was necessary. (mach/mx27.h and mach/mx31.h #include <linux/io.h> which
#includes <mach/io.h>. So mach/mxc.h which provides the cpu_is_ macros
needs to be included before mach/mx27.h and mach/mx31.h.)

Since support for mxc91231 was introduced 2009 it only saw patches that
were part of (mxc or arm) global cleanups. The only supported machine
only had 4 devices (2x UART, sdhc, watchdog).

Now only the virtual addresses [0xf4000000, 0xf5ffffff] are used for
static per-SoC mappings. The few mappings of whole chip selects are
moved accordingly.
The now wrong defines for virtual base addresses are removed.

This makes less code rely on the virtual constants.
To further simplify code and reduce the needed boilerplate when
defining the static mappings a new helper macro is defined in
mach/hardware.h.

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.

This patch moves the stuff common to i.MX31 and i.MX35 to mx3x.h and the
specifics to mx31.h/mx35.h. We can build a kernel which runs on i.MX31 and
i.MX35, so always include mx31.h and mx35.h

* define new CONFIG_ARCH_MX21 (this one is currently mutually exclusive to
CONFIG_ARCH_MX27, but this might change)
* splits one header file. Memory definitions, interrupt sources,
DMA channels are split into common part, i.MX27 specific and i.MX21
specific.
* guard access to UART5/UART6, which don't exist on i.MX21

Adds MX1 architecture to platform MXC. It will supersede mach-imx
and let it die.
