soc/amd: Use fixed EFS location for Phoenix & Glinda

The AMD SoCs no longer have a variable position for EFS - it's now fixed
at 0xff020000 - 128KiB into the 16MiB ROM decode region.

It's a little more complex than that because the chip can be larger than
16MiB, and the entire ROM can be decoded if mapped above the 4GiB
boundary, but we don't currently support doing that in coreboot, so this
is enough for now.
