This patch adds some testcases for dtc's -Oasm mode. Specifically it checks that building the asm will result in the same device tree blob in memory as -Odtb mode would produce, for a variety of trees. This test uncovered two difficulties with our current -Oasm output, both of which are addressed in this patch as well. First, -Oasm output would only be correct if assembled for a big-endian target. Usually that would be the case, when building device trees into a firmware or similar. However this makes life inconvenient for testing on a little-endian target, and one can think up use cases where a program running on a little endian host might want to embed a device tree for a big-endian target. This patch therefore changes -Oasm output to use .byte directives instead of .long throughout in order to generate byte-for-byte identical trees regardless of the endianness of the assembler target. Second, -Oasm output emitted several #define statements which were then used in the innards of the output - i.e. it assumed the output would be processed by cpp before being assembled. That may not be convenient in all build environments, and in any case doesn't work well with the above fix. So, -Oasm output no longer needs to be preprocessed before assembling.
