feat(fvp): drop usage of AArch32 specific DTs

There should be no difference in a devicetree between an OS using AArch32
and one using AArch64.
In preparation for unifying the DT generation in the TF-A tree, drop the
usage of the AArch32 specific version already. This should not have a
real effect on a half-way recent OS, and allows to remove those AArch32
specific DT files from the TF-A tree completely.
