[coreboot] Builds of Google boards fail due to FSP size

[Felix Singer]

Hello,

Moving forward the submodule pointers of the microcode [1] or Intel FSP
[2][3] repository will make the Google boards (ChromeOS builds?)
failing because the FSP does not fit into their flash region anymore.

How do we deal with that issue? I think there are two options:

* Make the flash regions bigger
  * Disable ChromeOS builds for upstream

Best

Felix
