amdfwtool: Change .rom.efs to .rom and .rom to .rom.body 

To support 32M flash, the non-vboot also need to split amdfw.

The amdfw.rom is the default filename added to CBFS.
Keep the default filename and then we don't have to change all the
CBFS definition.

This is one of series of patches to support 32/64M flash.
