This adds a helper function for long mode to call some code in protected
mode and return back to long mode.
The primary use case is to run binaries that have been compiled for
protected mode, like the FSP or MRC binaries.
Tested on Intel Skylake. The FSP-M runs and returns without error while
coreboot runs in long mode.

Add support for devices with the reset vector pointing into DRAM. This
is a specific implementation that assumes a paradigm of AMD Family 17h
(a.k.a. "Zen"). Until the first ljmpl for protected mode, the core's
state appears to software like other designs, and then the actual
physical addressing becomes recognizable.
These systems cannot implement cache-as-RAM as in more traditional
x86 products. Therefore instead of reusing CAR names and variables,
a substitute called "earlyram" is introduced. This change makes
adjustments to CAR-aware files accordingly.
Enable NO_XIP_EARLY_STAGES. The first stage is already in DRAM, and
running subsequent stages as XIP in the boot device would reduce
performance.
Finally, add a new early_ram.ld linker file. Because all stages run in
DRAM, they can be linked with their .data and .bss as normal, i.e. they
don't need to rely on storage available only at a fixed location like
CAR systems. The primary purpose of the early_ram.ld is to provide
consistent locations for PRERAM_CBMEM_CONSOLE, TIMESTAMP regions, etc.
across stages until cbmem is brought online.
