Generate SB file for FlexSPI NOR Image encryption and programming

Usually, a BD file for FlexSPI NOR image encryption and programming consists of 7 steps.

1. The bootable image file path is provided in sources block.

2. Enable FlexSPI NOR access using FlexSPI NOR Configuration Option block.

3. Erase the flash device if it is not blank. The erase operation is time consuming and is not required for a blank flash device (factory setting) during manufacturing.

4. Enable image encryption using PRDB option block.

5. Program FNORCB using magic number.

6. Program boot image binary into Serial NOR via FlexSPI module.

7. Enable Encrypted XIP fuse bits.
