[PATCH v2] dts: nxp: mxs: Fix partitions definitions and remove saif (imx28-lwe.dtsi)

From: Lukasz Majewski
Date: Tue Aug 27 2024 - 11:11:11 EST


The SPI-NOR memory layout has evolved during time lifetime of the
device - for example special partitions to keep track of booted devices
for A/B booting scheme were added.

Additionally the saifX nodes are specific to other group of the imx287
based devices, so needs to be moved to different devices description.

Changes for v2:
- Add more descriptive commit message
- Replace e.g. partition@4 with partition@fe0000
