Re: dtc: Make helper macros in trees.S more flexible

So, like, the other day David Gibson mumbled:

This patch makes the helper macros in trees.S use separate labels for
the end of each dt subblock, rather than using only start labels.
This means that the macros can now be used to create trees with the
subblocks in non-standard orders.

In addition, it adds a bunch of extra ; after lines of asm code in
macros, making them safe to use in nested macros.

Applied.
