HACK: rearrange the virt memory map to suit OP-TEEmulti-ases-2
The current OP-TEE codebase expects the secure UART to
be at 0x09010000 and irq 2 (it is based on an old
non-upstream patch to add a second uart, and upstream
used that memory map area for something else). When
the TZ support is upstream in QEMU we can move OP-TEE
on to a proper upstream QEMU and update it to use the
new UART location, but for now this hack patch allows
running a more-or-less unmodified OP-TEE.
Put the secure UART at the address and irq where OP-TEE
expects it, moving some other devices down to make space.
