drivers: hwinfo: Add support for generating device id from device addr

In some ICs (including nRF54H20) the DEVICEID register is not part of
FICR, and thus it is not accessible to applications. Use instead the
device address, along with a couple of bytes from ER and IR, to
generated a unique device id.

At the same time update the pointer to the hal_nordic repo to pull in
zephyrproject-rtos/hal_nordic#196.

(cherry picked from commit ebd31d3)
