dtc: Remove some redundant testcases

This patch removes a number of testcases from the testsuite that are
extremely unlikely to find any bugs that won't be found by the other
tests.  This speeds up the testsuite.

	- Both loops across the various tree block layouts run the
tree1_tests on the basic mangled tree.  This is completely redundant,
so remove the second copy. This removes 456 testcases.

	- We currently run tree1_tests on various trees manipulated by
move_and_save.  We replace those with just a dtbs_equal_ordered test
to check that the manipulated tree is equal to the original.  What
we're testing here is that fdt_move() operates correctly - it's very
unlikely it would succeed well enough for the ordered_equal test to
succeed, but the tree1_tests would fail on the result.  This removes
162 testcases.

	- Currently we re-ordered with mangle-layout both the basic
test_tree1.dtb and sw_tree1.test.dtb.  Since we've already checked
that these dtbs are equivalent with dtbs_ordered_equal, it's very
unlikely that the tests would fail on one but not the other.
Therefore reduce this to only using test_tree1.dtb.  This removes 828
testcases.
