i.MX8 i.MX8X Board Reset

[#1]

In some cases, such as OTA, need a complete reset/reboot of the i.MX8/i.MX8X.

Current BSP default design for  i.MX8/i.MX8X is partition reset/reboot.

So even using spl bootloader(flash.bin).

The scfw is still running old version.

Not the upgrade version as expected.

Because the reset/reboot by the u-boot or Linux,

Only reset/reboot the A Core partition.

SCU is not reset.

Need to change to the board reset, which will launch entire reset/reboot of the i.MX8/i.MX8X including SCU.
