Changes in v4:
	- Rebased on linux-next

Changes in v3:
	- Fixed all comments and rebased on linux-next.
	- Removed WCSS userpd nodes from dtsi file,
	  because it vary based on no of radio's connected.
 
Changes in v2:
	- Corrected syntax like alignmnet and kept nodes in sorted
	  order.
	- Added 'firmware-name' property.
