[U-Boot] [PATCH V2 0/2] Add USB host support for CM-T35
Add USB host support for CM-T35. As a preparation, some register offset definitions are added to twl4030.h
Changes in V2: - Added GPIO register offsets for twl4030 - Used twl4030 definitions from patch 1 in twl4030 functions instead of BASE_ADDR + <numerical offset>

Dear Nikita Kiryanov,
Add USB host support for CM-T35. As a preparation, some register offset definitions are added to twl4030.h
Changes in V2:
- Added GPIO register offsets for twl4030
- Used twl4030 definitions from patch 1 in twl4030 functions instead of
BASE_ADDR + <numerical offset>
