dbeaca79b7 ARM: stm32: Factor out save_boot_params 
The STM32MP15xx platform currently comes with two incompatible
implementations of save_boot_params() weak function override.
Factor the save_boot_params() implementation into common cpu.c
code and provide accessors to read out both ROM API table address
and DT address from any place in the code instead.

bbafbc044d ARM: stm32: Fix ECDSA authentication with Dcache enabled 
In case Dcache is enabled while the ECDSA authentication function is
called via BootROM ROM API, the MMU tables are set up and the BootROM
region is not marked as executable, so an attempt to run code from it
results in a hang. Mark the BootROM region as executable as suggested
by Patrick to prevent the hang.
