Due to a typo, this code assumed so far ignored #size-cells and assumed
it to be equal to #address-cells. This breaks using the
barebox-dt-2nd.img with some 64-bit device trees like the Raspberry Pi's.

Instead of duplicating the loop for each of base and size, move it into
a helper function. This may come in handy later when extending the
function, e.g. to have the generic-dt-2nd image take /reserved-memory
entries into account and not rely on CONFIG_OPTEE_SIZE.

Including <stdio.h> for printf is a bit problematic, because it pulls in
other headers for <console.h>, which includes quite a few more headers
as well. To make it easier to share code between barebox and host tools
make <printk.h> the new minimal header for printf and move the extra
logging stuff into <linux/printk.h>.

Currently, the generic DT image can't properly have a PBL console,
because it's only known at runtime what system we are running on.
As we already parse the FDT in the PBL to get the memory regions, we
could extract the board compatible as well and determine which UART to
use. Add a helper to achieve this.

of_find_mem can be used for generic DT images for other architectures as
well. To support this, move the definition, so it can be used by others
in the future.
