[PATCH] ARM: fix DEBUG_UART_PHYS/VIRT issue when modifying DEBUG_LL output

Hello,

The DEBUG_UART_PHYS/VIRT value can only be automatically set once
(automatically means set from the DEBUG_<SOC_ID>_<UART_ID> option), which
prevents re-configuring the earlyprintk output for another platform once
the DEBUG_LL output has been selected.

Add a new boolean option (DEBUG_CUSTOM_UART_ADDR) enabling custom phys and
virt address setting (configured through DEBUG_CUSTOM_UART_PHYS/VIRT
options), and make DEBUG_UART_PHYS/VIRT hidden so that they will always be
set from one of the 'default' definitions, and thus will be overwritten
each time you change the DEBUG_LL output.

What is the status of this patch? It would actually be quite useful
when switching back and forth between different DEBUG_LL configurations.

Russell, what do you think of the proposed approach?

Thanks,

Thomas
