scripts: mkits.sh make it possible to specify fdt@# 

Some bootloaders are really keen on just one special
fdt in a multi-image fit image. This is a problem, because
currently this is fixed to "fdt@1".

This patch introduces a new device variable:
DEVICE_FDT_NUM that allows to specify the right
fdt number.

If the value is absent "1" will be chosen.
