Hi,

Here is an attempt to convert FAT filesystem configuraition to
kconfig. And switch of some TI platforms to use the newly introduced
support.

Tested on OMAP-L138 LCDK board. Build tested using:
$ tools/buildman/buildman am33 am43 omap davinci keystone

  fs: fat: add kbuild configuration support
  configs: k2*_evm: let each board decide env location
  configs: k2g_evm: make sure config fallbacks take effect
  config_fallbacks: add additional fallbacks for fat filesystem

  board: ti: enable support for writing to fat partition
  configs: omapl138_lcdk: enable fat filesystem support

Add Kconfig symbols for various configurations
supported by FAT filesystem support code.

CONFIG_SUPPORT_VFAT has been left out since its
force enabled in include/fat.h and probably
should get removed at some point.

Not all TI Keystone2 EVMs want environment in NAND flash.
K2G EVM which has an MMC/SD slot, keep environment in a
FAT partition on SD card.

Since ti_armv7_keystone2.h defines environment is in NAND,
boards which do not follow that have to #undef'ine that
configuration. This leads to ugly ordering issues around
where exactly the include of ti_armv7_keystone2.h can come
in within the k2*_evm.h files.

Move environment location to config file of each board.
This should make it easy to change it for any one board
without affecting all other boards.

Since config fallbacks contained in include/config_fallbacks.h
come into k2g_evm.h file through ti_armv7_keystone2.h, it should
be the last file included.

Without this, #define of FAT_WRITE when environment is in FAT
does not happen as the environment location is decided later
in the file.

Similar issues can come with other config fallbacks implemented.

Add fallbacks needed to keep all boards building
while they are migrated to use Kconfig symbols
instead of defines in <board>_config.h files for
FAT filesystem.

These should eventually go away once Kconfig select
or imply statements are put in place and duplicated
defines in <board>_config.h removed.

Now that there is Kconfig symbol available for
enabling FAT filesystem support, migrate to using
it for Siemens AM335x based boards.

I included the Kconfig logic here in the first patch in the series, and
then migrated it with everything else.

This really should be via CMD_FAT so that the code is used, as we have a
symbol for FS_FAT to use it with either of CMD_FAT or ENV_IS_IN_FAT.
Thanks!

Now that these symbols are in Kconfig, migrate all users.  Use imply on
a number of platforms that default to having this enabled.  As part of
this we must migrate some straglers for CMD_FAT and DOS_PARTITION.

This replaces the original 5/7 and migrates everything.
