Without this select the necessary DDR PHY firmware files will be missing
when only building for the i.MX8MM-EVK board.

i.MX8MM/MN/MP has UARTs in the same place in the MMIO address space as
the i.MX8MQ, so make the lowlevel debug a bit more generic across the
i.MX8M family.

v2:
- rebase on top of i.MX8MP support
- remove unused and redundant UART base address defines in SoC specific
headers, the shared define in the familiy header is fine

When the TF-A is configured to have some output on the UART it does not
set up the UART on its own, but just expects a pre-existing configuration.
If Barebox did not set up the UART in the !DEBUG_LL case, TF-A will just
hang without any user accessible debug output, which is a very non-obvious
failure, so better be safe and always set up the UART in case TF-A wants
to use it.

For whatever reason the i.MX8MM OCOTP got a separate compatible and
is not marked as compatible to imx8mq, while the parameters used in the
driver seem to be the same.
