feat(stm32mp2): add BL2 boot first steps
Configure the first steps for STM32MP2 BL2 platform boot:
- Save boot context address for later use
- Configure BL2 MMU
- Load and use BL2 DT
- Reset backup domain
- Initialize clocks
- Configure UART for console
- Print some info about board and reset reason
- Setup storage (only SD-card for the moment)
The platform boot stops at BL2 image load, as bl2_mem_params_descs[]
is still empty.
