The OTG hardware is a DWC2 controller and this series uses the existing gadget driver ("s3c_udc_otg.c").
Changes in v3: - use static inline functions instead of macros - update the delay (2ms) to match the kernel code - use "SZ_1M" - undefine the 8-bit phy interface
Changes in v2: - rebased against u-boot-dfu
