Subject: [RESEND v2 0/2] w1: Add AXI 1-wire host driver for AMD programmable logic IP core

Changes since v1:
 Updated IP name and binding to axi-1wire-host and filenames to match  Comment pruning where operation obvious, additional comments where not  Unwrapped helper functions for register read/writes  Removed un-necessary device reset on fail to add device  Fixed duplicate clock disable in remove function  Move bus master structure to per instance  Improved hardware testing with multiple w1 instances

Add a host driver to support the AMD 1-Wire programmable logic IP block.
This block guarantees protocol timing for driving off-board devices such as thermal sensors, proms, etc.
