Initialize extpower module prior to modules with default priority
This ensures that modules with default priority (or later) get
an accurate response from extpower_is_present().
BUG=chrome-os-partner:27160
BRANCH=ToT
TEST=Add a default priority initializer. Verify it gets the correct
value for extpower_is_present() with and without external power
connected.
static void extpower_init_check(void)
{
CPRINTF("[%T Extpower %s]\n", extpower_is_present() ? "on" : "off");
}
DECLARE_HOOK(HOOK_INIT, extpower_init_check, HOOK_PRIO_DEFAULT);
