ARM: at91: debug_ll: make UART base address configurable
This is in line with other platforms such as i.MX, which allow
specifying a debug port. As we can't use port indices because
the UARTs aren't mapped consecutively, allow specifying a hex
base at configuration time.
A side effect of this patch is that sama5d4's HAVE_AT91_DBGU2
is now honored as well. Previously anything besides DBGU0
defaulted to DBGU1.
Fixes: 06a0773ee31 ("ARM: at91: add sama5d4 soc support #2")
