arm: stm32mp: bsec: add permanent lock support in bsec driver

Add BSEC lock access (read / write) at 0xC0000000 offset of misc driver.
The write access only available for Trusted boot mode, based on new
SMC STM32_SMC_WRLOCK_OTP.

With the fuse command, the permanent lock status is accessed with
0x10000000 offset (0xC0000000 - 0x8000000 for OTP sense/program
divided by u32 size), for example:

Read lock status of fuse 57 (0x39)

  STM32MP> fuse sense 0 0x10000039 1

  Sensing bank 0:

  Word 0x10000039: 00000000

Set permanent lock of fuse 57 (0x39)

  STM32MP> fuse prog 0 0x10000039 1

  Sensing bank 0:

  Word 0x10000039: 00000000

WARNING: the OTP lock is updated only after reboot

WARING: Programming lock or fuses is an irreversible operation!
        This may brick your system.
