meta-ampere: mtjade: flash UEFI firmware at 4MB offset
UEFI firmware for Ampere Altra-based platform starts at offset 0x400000
but currently the firmware image is flashed start at offset 0. This
makes the Host fail to boot.
This commit supports offset option for the mtd-util's flashcp utility
and update the script to flash UEFI firmware starting at offset
0x400000.
Tested:
1. Turn on the Host.
2. Flash UEFI firmware. Wait for the flash complete and check if Host
can boot successfully.
4. Turn off the Host.
5. Flash UEFI firmware. Wait for the flash complete.
6. Turn on the Host and check if Host can boot successfully.
