[U-Boot] [PATCH v2 4/4] spl: fat/fs: Add control to build FS EXT4 in SPL

[tien.fong.chee at intel.com]

From: Tien Fong Chee <tien.fong.chee at intel.com>

CONFIG_SPL_FS_EXT4 can be used to include/exclude the FS EXT4 from
SPL build. Excluding the FS EXT4 from SPL build can help to save 20KiB
memory.

Signed-off-by: Tien Fong Chee <tien.fong.chee at intel.com>

changes in v2:
- Changed both config checking SPL_BUILD and FS_EXT4 to
  CONFIG_IS_ENABLED(FS_EXT4).
