meta-ampere: mtjade: Add more Host firmware support

Add support SCP firmware update with checking if the ampere_fru_upgrade
available to execute the update.
This commit also supports 2nd Host SPI-NOR update ability.

Tested:
1. Manually copy ampere_fru_upgrade to the /usr/sbin folder and run SCP
firmware update via Redfish.
2. Flash UEFI firmware update on the secondary Host SPI-NOR.

-Subject: [PATCH] flashcp support offset option
-
-The flashcp command from mtd-utils just support to flash from offset 0.
-Add offset option to specify the start offset so that firmware can be
-flashed correctly
