build system: Switch to fmap based firmware layout
We still add a master header for compatibility purposes, and the default
layouts don't cover anything non-coreboot (eg. IFD regions) yet.
The default layouts can be overridden by specifying an fmd file, from
which the fmap is generated.
Future work:
- map IFD regions to fmap regions
- non-x86: build minimalistic trampolines that jump into the first cbfs
file, so the bootblock can be part of CBFS instead of reserving a
whole 64K for it.
- teach coreboot's cbfs code to work without the master header
- teach coreboot's cbfs code to work on different fmap regions
