Subject: [Patch v4 4/5] ARM: dts: keystone: update reset node to work with reset driver

The keystone driver requires the next additional properties:

"ti,syscon-pll" - syscon register range used to access pll controller
		  registers in order to use reset control registers.
"ti,syscon-dev" - syscon register range used to access device state
		  control registers in order to use mux block
		  registers for all watchdogs.

"ti,wdt_list"	- option to declare what watchdog are used to reboot
		  the SoC, so set "0" WDT as default.
