meta-ampere: mtjade: change to use 64MB layout

As more features added to Mt.Jade OpenBMC, 32MB is not enough anymore.
In addition, the Mt.Jade has 64MB SPI-NOR for BMC firmware.
This commit changes to use 64MB BMC layout to have more room for
incoming features.

Tested:
1. Compile the firmware, flash to Mt.Jade BMC from u-boot and check if
it can boot to Linux successfully.
2. Compile another image and check if firmware update works fine.
