Refactor OMAP3/4/5 code so that we have only one get_device_type()
function for all platforms.
Details:
- Add ctrl variable for AM33xx and OMAP3 platforms (like it's done for
OMAP4/5), so we can obtain status register in common way
- For now ctrl structure for AM33xx/OMAP3 contains only status register
address
- Run hw_data_init() in order to assign ctrl to proper structure
- Remove DEVICE_MASK and DEVICE_GP definitions as they are not used
(DEVICE_TYPE_MASK and GP_DEVICE are used instead)
- Guard structs in omap_common.h with #ifdefs, because otherwise
including omap_common.h on non-omap4/5 board files breaks compilation
Buildman script was run for all OMAP boards. Result output:
arm: (for 38/616 boards)
all +352.5
bss -1.4
data +3.5
rodata +300.0
spl/u-boot-spl:all +284.7
spl/u-boot-spl:data +2.2
spl/u-boot-spl:rodata +252.0
spl/u-boot-spl:text +30.5
text +50.4

[trini: Rework the guards as to not break TI81xx]
Signed-off-by: Tom Rini <trini@konsulko.com>
The ti816x/am389x SoC is the first generation in what U-Boot calls the
"am33xx" family. In the first generation of this family the DDR
initialization sequence is quite different from all of the subsequent
generations. Whereas with ti814x (second generation) we can easily work
the minor differenced between that and am33xx (third generation), our
attempts to do this for ti816x weren't sufficient. Rather than add a
large amount of #ifdef logic to make this different sequence work we add
a new file, ti816x_emif4.c to handle the various required undocumented
register writes and sequence and leverage what we can from
arch/arm/mach-omap2/am33xx/ddr.c still. As DDR2 has similar problems
today but I am unable to test it, we drop the DDR2 defines from the code
rather than imply that it works by leaving it. We also remove a bunch
of other untested code about changing the speed the DDR runs at.

chiliSOM is a System On Module (http://http://grinn-global.com/chilisom/).
It can't exists on its own, but will be used as part of other boards.
Hardware specification:
* TI AM335x processor
* 128M, 256M or 512M DDR3 memory
* up to 256M NAND
We place source inside arch/arm/mach-omap2/ directory and make it
possible to reuse initialization code (i.e. DDR, NAND init) for all
boards that use it.

This moves what was in arch/arm/cpu/armv7/omap-common in to
arch/arm/mach-omap2 and moves
arch/arm/cpu/armv7/{am33xx,omap3,omap4,omap5} in to arch/arm/mach-omap2
as subdirectories. All refernces to the former locations are updated to
the current locations. For the logic to decide what our outputs are,
consolidate the tests into a single config.mk rather than including 4.
