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