- Complete the migration to LIBATA requiring BLK to be enabled.
- Complete the migration to DM_MMC being required for non-SPL/TPL
  U-Boot.

As it has been now two years past the migration deadline, it is required
to have migrated.  Remove the check from the Makefile and rework some of
the Kconfig logic slightly to get the functional dependencies of DM_MMC
/ BLK right in both the SPL and non-SPL case.

The migration deadline for having LIBATA mean that AHCI is also enabled
was v2019.07.  As that has long since passed, adjust the Kconfig

There are a number of platforms that depend on a SATA driver that has
been converted to require AHCI but the platforms themselves are behind
on other migrations that would make it trivial to enable AHCI.  Disable
SATA in these cases.

These specific configs are missing a number of migrations.  In addition,
they are blocking completion of the now-expired DM_MMC migration as it
requires enabling BLK.

This change would enhance the existing 'gpt read' command to allow
(optionally) writing of the read GPT partitions to an environment
variable in the UBOOT partitions layout format. This would allow users
to easily change the overall partition settings by editing said variable
and then using the variable in the 'gpt write' and 'gpt verify' commands.

[trini: Conditionalize the test being linked in]
Signed-off-by: NTom Rini <trini@konsulko.com>

It can be useful to use the same U-Boot binary for multiple purposes,
say the normal one, one for developers that allow breaking into the
U-Boot shell, and one for use during bootstrapping which runs a
special-purpose bootcmd. Or one can have several board variants that
can share almost all boot logic, but just needs a few tweaks in the
variables used by the boot script.

To that end, allow the control dtb to contain a /config/enviroment
node (or whatever one puts in fdt_env_path variable), whose
property/value pairs are used to update the run-time environment after
it has been loaded from its persistent location.

The indirection via fdt_env_path is for maximum flexibility - for
example, should the user wish (or board logic dictate) that the values
in the DTB should no longer be applied, one simply needs to delete the
fdt_env_path variable; that can even be done automatically by
including a

  fdt_env_path = "";

property in the DTB node.
