Revert "common: resource: print conflicts as warning"
On several i.MX boards we register SDRAM with the values
from the SDRAM controller and also with values from the
device tree. This now issues a warning each time the board
is started. Revert the commit for now.
A better solution might be to check if the same SDRAM region
already exists before trying to register it again.
This reverts commit c9e2e08.
