Enable support for writing to FAT partitions on
TI's boards.

Signed-off-by: Sekhar Nori <nsekhar@ti.com>

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.

[trini: Update logic since CMD_FAT / CONFIG_SPL_FAT_SUPPORT are
        selecting FS_FAT]
Signed-off-by: Tom Rini <trini@konsulko.com>

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.

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.

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.
