From: Jim Quinlan <jquinlan@xxxxxxxxxxxx>
- Add compatible strings for three more Broadcom STB chips: 7278, 7216,
7211 (STB version of RPi4).
- add new property 'brcm,scb-sizes'
- add new property 'resets'
- add new property 'reset-names' for 7216 only
- allow 'ranges' and 'dma-ranges' to have more than one item and update
the example to show this.
