54aa07fdfc sysinfo: Add gpio-sysinfo driver
This uses the newly-added dm_gpio_get_values_as_int_base3 function to
implement a sysinfo device. The revision map is stored in the device tree.

80a4570c99 x86: coral: Show memory config and SKU ID on startup
Provide the model information through sysinfo so that it shows up on
boot. For memconfig 4 pins are provided, for 16 combinations. For SKU
ID there are two options:

   - two pins provided in a ternary arrangement, for 9 combinations.
   - reading from the EC

Add a binding doc and drop the unused #defines as well.

Example:

   U-Boot 2021.01-rc5

   CPU:   Intel(R) Celeron(R) CPU N3450 @ 1.10GHz
   DRAM:  3.9 GiB
   MMC:   sdmmc@1b,0: 1, emmc@1c,0: 2
   Video: 1024x768x32 @ b0000000
   Model: Google Coral (memconfig 5, SKU 3)

This depends on the GPIO series:

3a8ee3df83 board: Rename uclass to sysinfo
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.
