Report the usage of the Advanced Sector Protection (PPB) to the user
upon 'flinfo' command. E.g:

Bank # 1: CFI conformant flash (16 x 16)  Size: 64 MB in 512 Sectors
  AMD Standard command set, Manufacturer ID: 0x01, Device ID: 0x227E2301
  Advanced Sector Protection (PPB) enabled
  Erase timeout: 16384 ms, write timeout: 2 ms
  Buffer write timeout: 5 ms, buffer size: 32 bytes

  Sector Start Addresses:
  FC000000 E      FC020000 E RO   FC040000 E      FC060000 E      FC080000 E
  ...
