Since commit 29d2d64ed5 ("x86: Add support for more than 8 MTRRs"),
the maximum number of variable range MTRRs was increased from 8 to 10.
On the BayTrail platform there are only 8 variable range MTRRs. In
mtrr_commit() it still uses MTRR_MAX_COUNT which caused a #GP during
VESA video driver probe. It should have been updated to use dynamically
probed number.
This fixes the boot failure seen on Intel Minnow Max board.

At present CONFIG_CHROMEOS is used to determine whether verified boot is
in use. The code to implement that is not in U-Boot mainline.
However, it is useful to be able to boot a Chromebook in developer mode
in U-Boot mainline without needing the verified boot code.
To allow this, use CONFIG_CHROMEOS_VBOOT to indicate that verified boot
should be used, and CONFIG_CHROMEOS to indicate that the board supports
Chrome OS. That allows us to define CONFIG_CHROMEOS on coral.

Most x86 boards build a u-boot.rom which is programmed into SPI flash. But
this is not unique to x86. For example some rockchip boards can also boot
from SPI flash.
Also, at least on x86, binary blobs are sadly quite common. It is not
possible to build a functional image without them, and U-Boot needs to
know this at build time.
Introduce a new CONFIG_HAS_ROM option which selects whether u-boot.rom is
built and a new CONFIG_ROM_NEEDS_BLOBS option to indicate whether binary
blobs are also needed. If they are not needed, it is safe to build the ROM
always. Otherwise we still require the BUILD_ROM environment variable.
For now this affects only x86, but future patches will enable this for
rockchip too.
