Change one-wire bus to use normal gpio interface
There's no need for it to directly access the GPIO registers. That
was only necessary at the beginning of link, when gpio_set_flags()
didn't exist.
BUG=chrome-os-partner:21612
BRANCH=none
TEST=onewire red / onewire green / onewire yellow all set the adapter LED
(tested on link, since I don't have a bolt, but the EC chip and adapter
are identical)
