This uclass is intended to provide a way to obtain information about a
U-Boot board. But the concept of a U-Boot 'board' is the whole system,
not just one circuit board, meaning that 'board' is something of a
misnomer for this uclass.

In addition, the name 'board' is a bit overused in U-Boot and we want to
use the same uclass to provide SMBIOS information.

The obvious name is 'system' but that is so vague as to be meaningless.
Use 'sysinfo' instead, since this uclass is aimed at providing information
on the system.

Rename everything accordingly.

Note: Due to the patch delta caused by the symbol renames, this patch
shows some renamed files as being deleted in one place and created in
another.

At present the top of available DRAM is the same as the top of the range
of the low-memory MTRR.

In fact, U-Boot is allowed to use memory up until the start of the FSP
reserved memory. Use that value for low_end, since it makes more memory
available.

Keep the same calculation as before for mtrr_top, i.e. the top of
reserved memory.

A side-effect of this change is that the E820 tables have a single entry
that extends from the bottom of the memory used by U-Boot to the bottom
of the FSP reserved memory. This includes the bloblist, if ACPI tables
are placed there.

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.

At present all tables are placed starting at address f0000 in memory, and
can be up to 64KB in size. If the tables are very large, this may not
provide enough space.

Also if the tables point to other tables (such as console log or a ramoops
area) then we must allocate other memory anyway.

The bloblist is a nice place to put these tables since it is contiguous,
which makes it easy to reserve this memory for linux using the 820 tables.

Add an option to put some of the tables in the bloblist. For SMBIOS and
ACPI, create suitable pointers from the f0000 region to the new location
of the tables.
