Re: libfdt: Test rw functions on more trees

So, like, the other day David Gibson mumbled:

At present, the testcases for read/write functions (setprop,
del_property and del_node) are only invoked on the single
asm-generated tree, not on any of the other tree images which should
be equivalent.  The functions in question will (correctly) not work on
the "unfinished" tree output from sw_tree1, but should work on most of
the others.

This patch extends the run_tests script to invoke the r/w testcases on
more example trees.  The testsuite still passes clean with this
addition.

Signed-off-by: David Gibson <redacted>

Applied.
