It may be beneficial to check if we can define it under nrf/soc/nordic/nrf54h

Automatically calculate LMA adjustment for firmware relocation.
If 'fw-to-relocate' chosen node exists, the firmware will be loaded
from the MRAM partition it points to, but will run from the TCM region
specified by 'zephyr,code-partition'.
Otherwise, uses standard calculation: 'code-partition' - 'sram'.
