STM32MP release v2.4-stm32mp1-r1

Rebase on official TF-A 2.4

Introduce a small generic clock framework
Add PIE support for BL32 (SP-MIN)

STM32MP1:
Update programmer (including FIP support)
Use FIP to manage BL2 load images (Split BL2/BL32)
Use FCONF feature to manage binaries policies
Update BL2 to be able to manage all trusted OS (SP_MIN or OP-TEE)
Clean up BL2 device tree for size optimization
Update BL2 MMU to minimize memory footprint
Update STM32 Crypto lib to use TBBR CoT authentication
Use the standard X509 certificate to authentify binaries using MBEDTLS
Define TZEN in BL32 based on RCC binding
Clean power sequence to move function into the BL32
Enable early watchdog interrupt to dump core debug information
Rework SSP support and include it in the default branch
Update STM32MP1 documentation
