refactor(stm32mp1): move stm32_save_boot_interface()

Browse source 
The function stm32_save_boot_interface()is moved to stm32mp1_private.c
file. The files stm32mp1_context.{c,h} are removed.
As return is always 0, change the function to return void.
Call it earlier, to be able to use it when configuring console.
