i.MX 7's Cortex-M4 core can run from DDR and uses DDR memory for
the rpmsg communication. Both use cases need a fixed location of
memory reserved. For the rpmsg use case the reserved area needs
to be in sync with the kernel's hardcoded vring descriptor location.
Introduce support for adding linux,usable-memory property to carve
out 1MB of memory in case the M4 core is running. Also make sure
that the i.MX 7 specific rpmsg driver does not get loaded in case
we do not carve out memory.

Add support for setting linux,usable-memory property in the memory
node of device tree for the kernel [1].
This property holds a base address and size, describing a
limited region in which memory may be considered available for use by
the kernel. Memory outside of this range is not available for use.

Please, don't pay attention to "android" keyword in the title
(actually nothing related to android), it's just a glitch.

Added again, and I have found that this breaks all boards where
CONFIG_ARCH_FIXUP_FDT_MEMORY is not set.
In fact, your new function calls fdt_pack_reg and this is not compiled
if the define above is not set. Just ask if it does not make sense to
let fdt_pack_reg() be always compiled...
Best regards,
Stefano Babic
