refactor(st): move FWU functions to common code
Move the platforms functions used for Firmware update in plat/st/common
directory. The function stm32mp1_fwu_set_boot_idx() is renamed
stm32_fwu_set_boot_idx() to align with other ones. A new function
stm32_get_bkpr_fwu_info_addr() is created to get the backup register
address where to store FWU info (counter and partition index).
