drivers: stm32_fmc: update and fix CID filtering configuration

The conditions to acquire or release RIF semaphores when applying
the CID filtering configuration were incorrect. Add
handle_available_semaphores() to handle correctly the RIF semaphores.
Also remove FMC_NB_MAX_CID_SUPPORTED and use generic MAX_CID_SUPPORTED.

drivers: stm32_fmc: do not make RIF configuration mandatory

It should not be mandatory to apply a RIF configuration for a FMC.
Remove this constraint by allocating a RIF configuration structure only
when the "st,protreg" property is present in the device tree to be
able to check if it has been allocated later.

drivers: stm32_rif: update and fix RIF configuration parsing

Fix the parsing of the RIF configuration by using device tree bindings,
when necessary. Generalize RIF bit fields and use them when dealing
with generic RIF functions. Update drivers that use stm32_rif_parse_cfg()
accordingly.

drivers: add FMC driver with RIF support

This driver implements RIF configuration for FMC, which is a RIF aware IP.
It means that the FMC driver is in charge of configuring its own RIF
restrictions and that the FMC has dedicated RIF configuration registers.

Additional check on RIF configuration is added for this IP when debug is
on.
