libfdt defined a new version of the flattened device tree format,
version 17. It is backwards compatible with version 16, just adding
an extra header field giving the size of the blob's structure blob.
This patch adds support to dtc allowing it to read and write version
17 blobs. It also makes version 17 the default output version for
blobs.
At the same time we change the code to consistently using decimal
numbers for versions. Previously we sometimes used 16 and sometimes
0x10 to refer to version 16.

The reserve mem regions are screwy if you read a blob on x86. I'm
guessing there may be a few more of these lurking in the code.

dtc always sets the physical boot CPU to 0xfeedbeef. Add a -b option to
set this. Also add warnings when using the wrong property with the
wrong blob version.

even for ASM output. It was inconsistent with the binary
output form, and kernel folks decided to have the early
kernel perform the reservation itself.
it shouldn't be (because the assembler will do the necessary swapping).
The cell values (asm_emit_cell()) are different from the data values
(asm_emit_data()) because the cell values are generated within the
program and don't get swapped like the data values read from the dts file.
They should be left as they are so that the assembler will swap them,
if necessary. For example, when the property length field was 4,
the asm output contained ".long 0x4000000" and sent the kernel prom.c
dt parsing code into the weeds.
