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.

Test HW: Odroid_XU3 (Exynos5422), trats (Exynos4210)

This patch enables all functions required to use DFU/THOR and UMS:
- DWC3: core, gadget, Samsung DWC3 PHY
- USB gadget: endpoint autoconf, downloader, DFU, THOR, UMS

The CONFIG_EXTRA_ENV_SETINGS from exynos5-common.h is redefined
and appended by dfu environment setting and some system settings.

The boot is still using $distro_boot as previous.
