Complete revamp of the exception entry code, including syscall handling.
Proper syscall frame exception trigger. Many correctness fixes, hacks
removal, etc. etc.
I tried to make this into several commits, but this stuff is all
inter-related and a pain to split.

Yes, that's more than a 10x speed-up!

Add initial support for the Salvator-X development board.
This work is strongly based on the H3ULCB board, but compared to it:
- device tree was enhanced
- adding all available push buttons and LEDs
- setting proper names according to the refdes used on the schematic and
PCB silkscreen
- documentation was adapted to this board

Update board flash partition to be compatible with v1.13.0 f/w.
This configuration is compatible with stm32wb5x_BLE_Stack_full_fw
which should be installed at 0x080C7000.

The pm_constraint_* APIs were effectively used by the policy manager
only. This patch renames the API to the policy namespace and makes its
naming more explicit:
- pm_constraint_set -> pm_policy_state_lock_get()
- pm_constraint_release -> pm_policy_state_lock_put()
- pm_constraint_get -> pm_policy_state_lock_is_active()
The reason for these changes is that constraints can be of many types:
allow/disallow states, impose latency requirements, etc. The new naming
also makes explicit that the API calls will influence the PM policy
behavior.
All drivers and documentation have been updated accordingly.

The Armv8R aarch64 is compiled with armv8.4-a, so the atomic_cas is
implemented by casal instruction, which needs FVP booting with
'-C bp.dram.enable_atomic_ops=1'
However, the FVP >= 11.17 has changed its parameters
'-C bp.dram.enable_atomic_ops' to '-C bp.s_dram.enable_atomic_ops' and
'-C bp.sram.enable_atomic_ops' to '-C bp.s_sram.enable_atomic_ops',
which is very annoying.
To fix this issue, disable LSE feature of GCC with 'armv8.4-a+nolse'.
