modules/linux: add support for building with kernel 5.4.69 (#854)

Browse Source 
* modules/linux: add support for building with kernel 5.4.69

Add support to module, port patches from 4.19.139.
Needed for newer platforms not supported by 4.19 kernel.

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

* CircleCI: add rysnc dependency for building kernel 5.x

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

* Migrate all Librem boards to kernel 5.x, common config

Update linux-librem_common.config from 4.x to 5.x, and add
CONFIG items needed to support the librem_l1um (AST DRM drivers,
serial port output).

Tested on Librem 13v4, Librem Mini, and Librem Server L1UM.
