PRM reset control dts changes for v5.5 merge window

This series of changes adds the PRM reset driver nodes for am3/4, omap4/5
and dra7 SoCs. The reset driver changes make it easier to add support for
various accelerators for TI SoCs in a more generic way.

Note that this branch is based on the PRM reset driver changes branch.

OMAP PRM instance bindings



Power and Reset Manager is an IP block on OMAP family of devices which

handle the power domains and their current state, and provide reset

handling for the domains and/or separate IP blocks under the power domain

hierarchy.



Required properties:

- compatible:	Must contain one of the following:

		"ti,am3-prm-inst"

		"ti,am4-prm-inst"

		"ti,omap4-prm-inst"

		"ti,omap5-prm-inst"

		"ti,dra7-prm-inst"

		and additionally must contain:

		"ti,omap-prm-inst"

- reg:		Contains PRM instance register address range

		(base address and length)



Optional properties:

- #reset-cells:	Should be 1 if the PRM instance in question supports resets.



Example:



prm_dsp2: prm@1b00 {

	compatible = "ti,dra7-prm-inst", "ti,omap-prm-inst";

	reg = <0x1b00 0x40>;

	#reset-cells = <1>;

};
