  Add BSEC support to STM32MP25 SoC family with SoC information:
- RPN = Device part number (BSEC_OTP_DATA9)
- PKG = package data register (Bits 2:0 of BSEC_OTP_DATA122)

DT looks good for me, and yaml verification is passed. Only thing to fix 
is the commit title. If you don't have to send a V2 for other remarks 
then I will fix during merge else fix it in your v2.

Thanks

Alex
