This adds the partitions definition for the SPI NOR to provide
backward compatibility with the documented[1] layout used with
Boundary Devices BSP.
1. https://boundarydevices.com/boot-flash-access-linux/
It exports to Linux:
mtd0: bootloader
mtd1: env
mtd2: splash

Changes in v4:
- drop lock flag
Changes in v3:
- use lock instead of read-only (Gary Bisson)
Changes in v2:
- rework labels (Fabio Estevam)
- add read-only flags (Fabio Estevam)
