[U-Boot] [PATCH v5 09/23] Declare watchdog functions in watchdog.h

Fri Feb 8 16:12:05 CET 2013
These functions are only available for powerpc and are not declared in a
header file. We want to use the rest function in two places (board_f and
board_r), so declare the functions in watchdog.h.

Changes in v5:
- Avoid using static declaration for init_func_watchdog_reset()
Changes in v4: None
Changes in v3: None
Changes in v2: None
