Reset controller changes for v5.3

This tag adds support for the Bitmain BM1880 reset controller to the
reset-simple driver and fixes a spelling mistake in the i.MX7 reset
controller binding document.

* tag 'reset-for-v5.3' of git://git.pengutronix.de/git/pza/linux:
  dt-bindings: reset: imx7: Fix the spelling of 'indices'
  reset: Add reset controller support for BM1880 SoC
  dt-bindings: reset: Add devicetree binding for BM1880 reset controller

Bitmain BM1880 SoC Reset Controller
===================================

Please also refer to reset.txt in this directory for common reset
controller binding usage.

Required properties:
- compatible:   Should be "bitmain,bm1880-reset"
- reg:          Offset and length of reset controller space in SCTRL.
- #reset-cells: Must be 1.

Example:

        rst: reset-controller@c00 {
                compatible = "bitmain,bm1880-reset";
                reg = <0xc00 0x8>;
                #reset-cells = <1>;
        };
