feat(stm32mp1): manage second NAND OTP on STM32MP13

On STM32MP13, 2 OTP fuses can be used to configure NAND devices.
By default OTP CFG9 is used for sNAND. A new OTP (CFG10) is used
to configure raw NAND. Thanks to bit 0 of CFG10 OTP, this default
configuration can be switched.
For sNAND on STM32MP13, the NAND_PARAM_STORED_IN_OTP is not used.
The sNAND parameters have to be taken from OTP bits.
