The ti816x SoC revision of the ethernet IP block is handled by the
"davinci_emac" driver, rather than the "cpsw" driver as done by later
members of the family. Enable the relevant plumbing.

- Switch to using <configs/ti_armv7_omap.h> and family. This lets us
drop lots of custom defines.
- Ensure that our default environment uses DEFAULT_LINUX_BOOT_ENV so
that Linux will boot correctly.
- Enable CONFIG_DISTRO_DEFAULTS
- Switch to using CONFIG_OF_CONTROL
- Various other cleanups to match other SoCs in the family line.

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.

Currently same value is programmed for all ioregs. This is not
the case for all SoC's like AM4372. So adding a structure for ioregs
and updating in all board files. And also return from config_cmd_ctrl()
and config_ddr_data() functions if data is not passed.

Based on the definitive guide to EMIF configuration[1] certain registers
that we have been modifying (and are documented registers) should be
left in their reset values rather than modified. This has been tested
on AM335x GP EVM and Beaglebone White.
