This patch renames all references of `top_of_ram` (TOM) in IA common
`basecode` module (for example: functions, variables, Kconfig,
Makefile and comments) with `ramtop` aka top_of_ram to make it more
meaningful and to avoid conflicts with Intel SA chipset TOM registers.
BUG=Able to build and boot google/rex with the same ~49ms savings
in place.

This patch implements a module that can store the top_of_ram (TOM)
address into non-volatile space (CMOS) during the first boot and
use it across all consecutive boot.
As top_of_ram address is not known until FSP-M has exited, it
results into lacking of MTRR programming to cache the 16 MB TOM,
hence accessing that range during FSP-M and/or late romstage causing
long access times.
Purpose of this driver code is to cache the TOM (with a fixed size of
16MB) for all consecutive boots even before calling into the FSP.
Otherwise, this range remains un-cached until postcar boot stage
updates the MTRR programming. FSP-M and late romstage uses this
uncached TOM range for various purposes (like relocating services
between SPI mapped cached memory to DRAM based uncache memory) hence
having the ability to cache this range beforehand would help to
optimize the boot time (more than 50ms as applicable).
TEST=Able to build and boot google/rex to ChromeOS.

The patch parses CPU and PCH Trace Hub modes from the debug area in the
Descriptor Region. The modes can be updated in the debug area in order
to configure the CPU and PCH Trace Hub modes. The debug area's offset
starts from the SPI Flash offset:0xf00.
For runtime debugging, the OEM Section in the Descriptor Region is being
used as debug area. The OEM Section details are documented in the SPI
Programmer Guide of CSE Lite kit.

The patch renames identifiers (macros, function and structure names) in
the basecode/debug/debug_feature.c to generic names so that they can be
used to control the features which may have to be controlled either
during pre and post memory.
Currently, the naming of identifiers indicate that it meant to control
the features which can be controlled during only pre-memory phase.

The patch adds a framework to control coreboot and Intel SoC features
dynamically. BIOS reads control information from OEM Section in the
Descriptor Region and control the developer selected features.
With the feature, debug team can control the selected SoC and coreboot
features without rebuilding coreboot.
In order to enable the feature, SOC_INTEL_COMMON_BLOCK_DEBUG_FEATURE has
to be selcted from mainboard.
The OEM section starts from offset:0xf00 till end of the Descriptor
Region(0xfff).
