[PATCH 1/3] ARM: dts: Add headers with constants for MTD partitions

[Florian Vaussard]

These constants can be used to easily declare MTD partitions inside
DTS.

The constants MTDPART_OFS_* are purposely not included. Indeed,
parse_ofpart_partitions() is expecting u64, but a DT cell is u32.
Negative constants, as defined by MTDPART_OFS_*, would be wrongly
interpreted by parse_ofpart_partitions(). Two cells should be
used to correctly encode the negative constants, but this breaks
current usage.
