Changes for v3:
- Remove unnecessary node from DT file
- Remove unnecessary features from config file
- Remove unnecessary macros from board-specific header file
- Fix some trivial typos in comments

Changes for v4:
- Add MMC FIFO buffer's configuration to DT file
- Make CONFIG_OF_CONTROL be set by the target information
- Add basic document to doc/README.odroid-xu3
- Add CONFIG_CMD_EXT4 to config file
- Add environment size and offset to config file
- Add extra default environment to make bootable without modification
- Remove unnecessary features from config file

Changes for v5:
- Convert /include/ to #include in DT file

Changes for v6:
- Separate out the documentation to new commit
- Remove unnecessary header file inclusions from the board-specific setup file
- Make the function board_clock_init be declared, only when
  CONFIG_BOARD_EARLY_INIT_F is defined

Changes for v7:
- Remove OF_CONTROL dependency from !SPL_BUILD

Changes for v8:
- Remove unnecessary properties in DT mmc node

Changes for v9:
- Remove useless variables in the default environment
- Replace the detailed information to the reference to the documentation

Changes for v10:
- Remove the config unsets which are added to make the result image small
  This is needless now, because the image is not small enough even though these
  unsets are added.
- Remove redundant DT node and properties
- Remove the odroid-xu3 board file and make odroid-xu3 a variant of smdk5420

Changes for v11:
- Remove duplicated CONFIG_CMD_EXT2/EXT4/FAT from odroid_xu3.h
- Fix the typo in the comment, which is found in odroid_xu3.h
