Merge https://gitlab.denx.de/u-boot/custodians/u-boot-x86

- Add a new SMBIOS parser and enable it when booting from coreboot
- Fix up various driver names to avoid dtoc warnings
- Fully enable ACPI support on Google Chromebook Coral
- Add a way to set SMBIOS properties using the devicetree
- Update existing boards to use devicetree for SMBIOS using a new
  default sysinfo driver
