dt-bindings: mtd: partitions: u-boot: allow dynamic subpartitions 



U-Boot partition may contain subpartitions. For example Broadcom
includes environment data block in the middle of its U-Boot partition.

This allows describing Broadcom's U-Boot env data and will allow
referencing its NVMEM cell in the future.
