cros_write_firmware: Extract FDT from image automatically

It is a pain to have to specify the board and FDT when writing an image.
Extract the FDT from the image instead, while still allowing an override
if required.

BUG=chromium:245311
BRANCH=none
TEST=manual
Using any image build from ToT, this command should flash it over USB:

$ cros_write_firmware /path/to/image.bin -F spi

For x86, this command should write it to em100:

$ cros_write_firmware /path/to/image.bin

Tested on pit and link.
