enabling the realtime clock 1-wire chip DS1307 and 1-wire on GPIO4 (as a module)
1-wire: Add support for configuring pin for w1-gpio kernel module
See: https://github.com/raspberrypi/linux/pull/457
Add bitbanging pullups, use them for w1-gpio
Allows parasite power to work, uses module option pullup=1
bcm2708: Ensure 1-wire pullup is disabled by default, and expose as module parameter
