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

[Lukasz Majewski]

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
- Use lower case letters for HEX offsets descriptions

It seems the patch should be split into two.

We idiomatically use subject prefix "ARM: dts: " for IMX/MXS DTS
changes, so I would suggest "ARM: dts: imx28-lwe: ..." here.
