[PATCH v3 0/4] Allow coreboot modules to autoload and enable cbmem in the arm64 defconfig

[Nícolas F. R. A. Prado]

This series adds the missing pieces to the coreboot bus and the module
alias generation to allow coreboot modules to be automatically loaded
when matching devices are detected.

The configs for cbmem coreboot entries are then enabled in the arm64
defconfig, as modules, to allow reading logs from coreboot on arm64
Chromebooks, which is useful for debugging the boot process.

Changes in v3:
- Merged all "add to module device table" commits into a single commit
  which also changes the coreboot_driver struct to contain an id table
  and avoid unused variable warnings for the id tables.

Changes in v2:
- Added commits for vpd, memconsole and framebuffer drivers to add them
  to the module device table
