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: imx_rngb: Switch to hw_get_random_bytes()

hw_get_random_byte() is no longer used. The default crypto_rng_read()
calls hw_get_random_bytes() now so we do not need to override this
and can simply implement just hw_get_random_bytes().

core_mmu: fix implicit behavior of core_mmu_add_mapping()

In core_mmu_add_mapping() requested physical address
rounded up/down to granule size (0x100000), which leads
to establishing of virtual mappings with overlapped
physical counterparts. If two virtual mappings overlaps
due to such roundings, then following phys_to_virt() can
implicitly return result of virtual address from
unexpected mapping. This patch fix such behavior by
returning virtual address of newly established mapping.
