This will implement a way of doing static initialization the "IAR" way. This is done by calling __iar_data_init3 which handles all static initialization that is mentioned in the linker file "initialize by copy". Signed-off-by: Robin Kastberg <robin.kastberg@iar.com>

IAR handles initialization of static variables.

Instead of `z_prep_c` calling Zephyrs `z_data_copy`
|
|
we call IARs own proprietary initialization method
|
|
which can save time and space.
