[PATCH 0/2] board: toradex: imx95: remove gpio1 reg

[Antoine Gouby]

This series removes gpio1 reg from Toradex SMARC iMX95 and Verdin iMX95
device trees.

The RGPIO2P driver contains legacy handling for compatible combinations
that expose two reg ranges (dual base) for i.MX8ULP and i.MX93.

The i.MX95 GPIO controller exposes a single register range, so the 
dual-base handling is unnecessary.

On Verdin iMX95, the second address of the gpio1 reg node was incorrect.
When used, it needs to be offsetted by 0x40 to start at the Port Data
Output register.
