[PATCH 1/2] ARM: i.MX8M: select ARM_USE_COMPRESSED_DTB for all boards

[Ahmad Fatoum]

With DDR firmware, ARM trusted firmware and possibly OP-TEE, we are
already quite short on SRAM, so it makes sense to always use compressed
device trees on the i.MX8M to shift some of the size from PBL into
barebox proper. Select ARM_USE_COMPRESSED_DTB for the i.MX8M boards.

Follow-up commit will touch all i.MX8M boards we have in tree that do
not yet make use of this.
