We don't have cpu_is_omapxxxx SoC detection initialized until
SoC detection is initialized from init_early.
Note that with the common map_io we should no longer need
cpu_is_omapxxxx for ioremap.

Otherwise we can't do generic map_io as we currently rely on
static mappings that work only because of arch_ioremap.

This assumes fixed mappings which will not work once we move
to use ioremap_exec(). It seems that these are currently
not in use, or in use for some out of tree corner cases.
If SRAM support for framebuffer is wanted, it should be done
with ioremap in the driver.
Note that further removal of the code can now be done,
but that can be done seprately by the driver maintainers.

This way we don't need to initialize SoC detection early
and can start using generic map_io.

This allows removing omap hacks for map_io allowing generic
map_io.
Note that in the future we can't do cpu_is_omapxxxx detection
until in init_early. This means that board-innovator.c now
assumes 15xx only, and board-generic.c assumes 16xx only.
This is best fixed later on by passing the SoC type from
device tree.

Given that we want the default to not have any <mach/memory.h> and given
that there are now fewer cases where it is still provided than the cases
where it is not at this point, this makes sense to invert the logic and
just identify the exception cases.
The word "need" instead of "have" was chosen to construct the config
symbol so not to suggest that having a mach/memory.h file is actually
a feature that one should aim for.

This also removes the mach/s3c2400 version which was probably never used
due to the fact that we have this line in arch/arm/Makefile:
machine-$(CONFIG_ARCH_S3C2410) := s3c2410 s3c2400 [...]
This is later used to construct the search path for:
The compiler would be looking into mach-s3c2410 and picking up this
version first. Any config that was actually expecting the mach-s3c2400
version was therefore producing a broken kernel binary. Not relying on
any of them anymore would fix that issue.

Re-cycle the original board-generic.c file to support Device Tree
for every OMAP2+ variants.
The current approach is an intermediate step before having only
one machine descriptor that will use some generic DT aware
functions.
