drivers: memc: MAX32 memc linker support improvements 



In order to allow the linker to place certain objects into external RAM,
e.g. heaps, adjust the memc initialization level to PRE_KERNEL_1, allowing
clock control and memc to come up before priority objects like heaps are
initialized.

	  If you want to rely on the linker to place symbols in this memory

	  (using`zephyr_code_relocate() or Z_GENERIC_SECTION()), you have to

	  ensure this driver in initialized before KERNEL_INIT_PRIORITY_OBJECTS

	  (=30). In addition, this driver depends on a clock, so you have to

	  ensure the clock will be started before this driver as well (see

	  CLOCK_CONTROL_INIT_PRIORITY)
