Subject: [PATCH] ARM: dts: aspeed: ibm: Use non-deprecated AT25 properties
The at25,* properties have been deprecated since 2012. These platforms
weren't upstream until 2020 and 2023, so it should be safe to switch
over to the "new" properties and just drop the deprecated ones.
Signed-off-by: Rob Herring (Arm) <robh@...nel.org>
