core: fix ASLR problem with short-descriptor table mappings

With short-descriptor table mappings, that is without LPAE, the user va
range is defined at the lowest addresses. Depending on the seed supplied
this could conflict with chosen base address for core mappings. Add a
check early in assign_mem_va() to avoid such conflicts.

Without this patch there's a risk of occasional panics like:
E/TC:0 0 Panic 'issue in linear address space' at core/arch/arm/mm/core_mmu.c:2147 <check_pa_matches_va>
E/TC:0 0 TEE load address @ 0xa34000

When using a devicetree, it is often useful to have clocks parsing.
This support adds clocks properties parsing and allow having clock
providers and users. Clocks drivers can also be declared with
CLK_DT_DECLARE. They will be probed automatically by the clock core.
On the user side, function clk_dt_get_by_name and clk_dt_get_by_idx
allows to retrieve a clock from the device tree description and match
it with the provider clocks. The core ensure the clocks are probed
hierarchically.
This support is enabled using CFG_DRIVERS_CLK_DT.
