Matt DeVillier 1174dad2e2 mb/purism/librem_mini: Enable DRAM Refresh2X
Enable Refresh2X to mitigate RAM corruption during long
(> 1hr) periods of S3/suspend, which leads to failure to
successfully resume from S3. Unknown if an issue with all
DRAM types, but tested w/Kingston KVR24S17D8 16GiB DDR4 SODIMMs.

Test: Build/boot Librem Mini v1/v2, put device in suspend,
wait > 1hr, ensure resume from S3 successful 100% of the time.
