Add new board: Purism Librem Mini (#806)

* patches/coreboot-4.12: Add patch for Cannonlake ME status

Add patch print ME status regardless of enablement state

Signed-off-by: Matt DeVillier <matt.devillier@puri.sm>

* modules: add purism-blobs module

Rather than require users to manually run a script to download the required
blobs to build Purism Librem boards, automate it so the correct version
is automatically downloaded/extracted. Restrict to coreboot 4.12 for now
since 4.8.1 still needs FSP blobs, which are not in module.

* configs/linux-librem13v2: unset CONFIG_RETPOLINE

Fixes compilation issue with newer kernels, ignored by older ones
which don't need it

Signed-off-by: Matt DeVillier <matt.devillier@puri.sm>

* Add new board: Librem Mini

Add Librem Mini board patch for coreboot 4.12, board config and
coreboot config. Continue reusing existing librem13v2 Linux config,
same as all other Librem boards currently. Use new purism-blobs module.

Signed-off-by: Matt DeVillier <matt.devillier@puri.sm>

* board/librem*: rename for consistency

Use 'librem_<board>' notation for consistency across all models.
Rename linux config file since used by multiple Librem models.

* CircleCI: add librem_mini board to test

Print the ME status even if the CSE device is disabled, so
we know which disabled state it's in.
