If there is a resource table device tree node, use the address as
the resource table address, otherwise use the address(where
.resource_table section loaded) inside the Cortex-M elf file.

And there is an update in NXP SDK that Resource Domain Control(RDC)
enabled to protect TCM, linux not able to write the TCM space when
updating resource table status and cause kernel dump. So use the address
from device tree could avoid kernel dump.

Note: NXP M4 SDK not check resource table update, so it does not matter
use whether resource table address specified in elf file or in device
tree. But to reflect the fact that if people specific resource table
address in device tree, it means people are aware and going to use it,
not the address specified in elf file.
