support blackfin board initialization in generic board_f
- init hardware watchdog if applicable - use CONFIG_SYS_MONITOR_LEN as the gd monitor len for Blackfin - reserve u-boot memory at the top field of the RAM for Blackfin - avoid refer to CONFIG_SYS_MONITOR_LEN, which is not defined by Blackfin Signed-off-by: Sonic Zhang <sonic.zhang@analog.com>
