Martin Fuzzey a2e99a71b2 w1: Add driver for i.MX bus master controller 
Two variants of controllers are supported:
V1 (bitwise only) found in
	i.MX21, i.MX27, i.MX31, i.MX51
V2 (byte operations) found in
	i.MX25, i.MX35, i.MX50, i.MX53

Only tested on i.MX53 hardware but in both modes
(by modifying the device tree).

We might want to use 1-Wire devices connected on boards such as EEPROMs in
U-Boot.

Provide a framework to be able to do that.
