w1: add 1-wire master driver for IP block found in SGI ASICs
Starting with SGI Origin machines nearly every new SGI ASIC contains an 1-Wire master. They are used for attaching One-Wire prom devices, which contain information about part numbers, revision numbers, serial number etc. and MAC addresses for ethernet interfaces. This patch adds a master driver to support this IP block. It also adds an extra field dev_id to struct w1_bus_master, which could be in used in slave drivers for creating unique device names.
