This converts the brcm,bcm2835-pm bindings from text to proper schema.

-BCM2835 PM (Power domains, watchdog)
-
-The PM block controls power domains and some reset lines, and includes
-a watchdog timer.  This binding supersedes the brcm,bcm2835-pm-wdt
-binding which covered some of PM's register range and functionality.
-
-Required properties:
-
-- compatible:		Should be "brcm,bcm2835-pm"
-- reg:			Specifies base physical address and size of the two
-			  register ranges ("PM" and "ASYNC_BRIDGE" in that
-			  order)
-- clocks:		a) v3d: The V3D clock from CPRMAN
-			b) peri_image: The PERI_IMAGE clock from CPRMAN
-			c) h264: The H264 clock from CPRMAN
-			d) isp: The ISP clock from CPRMAN
-- #reset-cells: 	Should be 1.  This property follows the reset controller
-			  bindings[1].
-- #power-domain-cells:	Should be 1.  This property follows the power domain
-			  bindings[2].
-
-Optional properties:
-
-- timeout-sec:		Contains the watchdog timeout in seconds
-- system-power-controller: Whether the watchdog is controlling the
-    system power.  This node follows the power controller bindings[3].
