binman: Simplify state.fdt_subset

Browse Source 
At present this excludes the device tree passed in to binman since it
is always returned first by GetAllFdts(). However, this is easy to ensure
by adding a check in that function. Change this dict to includes all
device trees, and rename it to fdt_set.
