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.
