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: clk: change clk_dt_get_by_*() prototype

Changes clk_dt_get_by_idx() and clk_dt_get_by_name() to return a
the TEE_Result code and use an output argument to pass back
clock reference rather than the opposite. This change makes
clk_dt_get_by_*() function more consistent with the other
OP-TEE core API functions.

Also renames clk_dt_get_by_idx() to clk_dt_get_by_index().

Updates sama5d2_clk.c and atmel_trng.c accordingly.
