Merge patch series "arm: dts: sc5xx: device tree updates and fixes"

Browse Source 
Ozan Durgut <ozan.durgut@analog.com> says:

This series introduces updates for Analog Devices SC5xx boards.

It cleans up device trees by renaming GPIO expanders and removing
incorrect SPI flash definitions from the common include file.

For the SC598, this series updates the EZLITE board to the latest
Revision E hardware. It also adds missing GPIO hogs and enables
additional commands for the EZKIT configuration.
