[U-Boot] [PATCH] 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_EXT_SUPPORT 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.
