The declaration of otg*_plat and otg*_board_data is guarded by
CONFIG_USB_MUSB_*, but their use in arch_misc_init is not. The
ifdef flow goes something like:

if (CONFIG_USB_MUSB_* && other_conditions)
	declare usb_data
if (other_conditions)
	use usb_data

Thus when CONFIG_USB_MUSB_* is not declared, we try to use the
data structures, but these structures aren't defined.

To fix this, move the USB initialization code into the same #ifdef
which guards the declaration of the data structures. Since the DM_USB
vs legacy cases are completely different, use two versions of
arch_misc_init(), for readability.

The TI816x has 2 GPIO banks.  For bank 0 we had been clearing the enable
bit when setting BIT(8).  Correct this by setting it to BIT(1) | BIT(8)
after we set and wait for BIT(1) (aka PRCM_MOD_EN).  Enable GPIO1 as

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

The symbol CONFIG_TI81XX is used for the parts that are common to the

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.

While in theory this value could be used in places outside of "omap5"
(such as OMAP4), we only make use of it today in OMAP5, so place the
Kconfig entry there.  Given that Kconfig lets us provide a default, we
drop CONFIG_DEFAULT_OMAP_RESET_TIME_MAX_USEC entirely.  The contents of
doc/README.omap-reset-time make a good help entry, so adjust them
slightly and delete the file.  Move the comment about range to where we
use the value now, and have Kconfig enforce the upper bound.
