ARM: dts: stm32: fullfill diversity with OPP for STM32M15xF SOCs

This commit creates new file to manage security features and supported OPP
on STM32MP15xF SOCs. On STM32MP15xY, "Y" gives information:
-Y = A means no cryp IP and no secure boot + A7-CPU@650MHz.
-Y = C means cryp IP + optee + secure boot + A7-CPU@650MHz.
-Y = D means no cryp IP and no secure boot + A7-CPU@800MHz.
-Y = F means cryp IP + optee + secure boot + A7-CPU@800MHz.

It fullfills the initial STM32MP15x SoC diversity introduced by
commit 0eda69b6c5f9 ("ARM: dts: stm32: Manage security diversity
for STM32M15x SOCs").
