Make ASSERT() report assertion failures
Rather than just reset the board, report assertion failures to aid
debugging. To enable this, use CONFIG_ASSERT_HELP.
BUG=chrome-os-partner:10149
TEST=manual

and see the a nice message is printed now.
ASSERTION FAILURE 'address' in command_read_word() at common/memory_commands.c:00000037
