tree-wide: remove useless newline character in *MSG() messages

The *MSG() macros take care of printing a newline. Adding a newline
character ('\n') is useless. Remove it.

core: replace _fdt_ prefix with fdt_ for device tree API

As per upstream discussion, there is no reason to keep _fdt_ prefix.
Replaces it with fdt_ for all occurrences.

core: dt: Make it possible to alter device mapping

In case where IP core device is TrustZone aware and is used by both REE
and TEE dt_map_dev() would normally cause non-secure mapping for the
device.

When selected registers in IP core are only accessible by TrustZone device
needs to be mapped with MEM_AREA_IO_SEC to cause actual AXI memory access
be made with AWPROT[1] and ARPROT[1] bits configured properly.

This adds new argument for dt_map_dev() to enable forcing mapping to be
secure or non-secure.

drivers: xiphera_trng: Allow interrupts while waiting for random

If for some reason getting new random values take a bit longer toggle
interrupt masks on/off while waiting.

This allows pending interrupts to be served faster in REE side as getting
new random might not be that important. At the same time it gives more
time for random number generation to complete and not just performing
spinning and waiting.

It was originally recommended by TRNG vendor not to cache previous partial
results in memory. TRNG itself is rather fast so there should
be always fresh bytes available for consumption. Thus to simplify the code
remove the FIFO construct.
