1611c8cbcf exynos5-dt-types: add board detection for Odroid XU3/XU3L/XU4.
This commit adds additional file with implementation of board
detection code for Odroid-XU3/XU4.

The detection depends on compatible found in fdt:
- "samsung,exynos5" - uses Exynos5 generic code
- "samsung,odroidxu3" - try detect XU3 revision

There are few revisions of Odroid XU3/XU4, each can be detected
by checking the value of channel 9 of built-in ADC:
 Rev   ADC  Board
 0.1     0  XU3 0.1
 0.2   372  XU3 0.2 | XU3L - no DISPLAYPORT
 0.3  1280  XU4 0.1

The detection code depends on the ADC+10% value.

Implementation of functions:
- set_board_type()     - read ADC and set type
- get_board_rev()      - returns board revision: 1..3
- get_board_type()     - returns board type string

Additional functions with return values of bool:
- board_is_generic()   - true if found compatible "samsung,exynos5"
                         but not "samsung,odroidxu3"
- board_is_odroidxu3() - true if found compatible "samsung,odroidxu3"
                         and one of XU3 revision.
- board_is_odroidxu4() - true if found compatible "samsung,odroidxu3"
                         and XU4 revision.

After I2C controller init, the get_board_type() can check
if the XU3 board is a "Lite" variant, by probing chip
0x40 on I2C0 (INA231 - exists only on non-lite).
This is useful for setting fdt file name at misc_init_r().

Enabled configs:
- CONFIG_ENV_VARS_UBOOT_RUNTIME_CONFIG
- CONFIG_ODROID_REV_AIN
- CONFIG_REVISION_TAG
- CONFIG_BOARD_TYPES

c65dc7d874 exynos: Add common board code for exynos5 boards that use device tree
Some boards use device tree for almost all board-specific configuration.
They therefore do not need their own separate board code, but can all use
the same version. Add a common version of the board code. It uses the
PMIC, regulator and video bridge uclasses. This will support smdk5250,
smdk5420, snow, spring, pit and pi.

01acd6abbd usb: USB download gadget and functions config options coherent naming
This introduces a coherent scheme for naming USB download gadget and functions
config options. The download USB gadget config option is moved to
CONFIG_USB_GADGET_DOWNLOAD for better consistency with other gadgets and each
function's config option is moved to a CONFIG_USB_FUNCTION_ prefix.

abfe8afe88 ums: move IO support code to common location
There's nothing Samsung-/board-specfic about the implementation of
ums_init(). Move the code into cmd_usb_mass_storage.c, so that it can
be shared by any user of that command.

4b19ed6c76 usb: ums: move ums code from trats to Samsung common directory
UMS init was implemented in trats board file but mostly it comprises
common code. Due to that it has been moved to common/ums.c to avoid
code duplication in the future.

Changes:
- move ums initialization code from trats to common/ums.c
- remove unused CONFIG_USB_GADGET_MASS_STORAGE from trats.h

Changes v2:
- move this patch at the top of code cleanups patches
