BIST (Built-In Self Test) is an IP responsible for triggering hardware
circuitry tests on both logic as well as memory blocks. This driver is
currently being upstreamed in U-Boot [1] (on hold till the dt-binding
is approved here) and triggers these tests on cores. This patch series
adds the dt-binding as well as a node for BIST on J784S4 and J742S2.

Changes since v3:

- Krzysztof
	- use existing common definition (ti,sci-dev-id) for grabbing
	  the device ID instead of redefining properties
