mb/purism/librem_skl: Enable and set SATA tuning params
Some Librems have issues with 6Gbps SATA operation on certain
SSDs, setting the Receiver Equalization Boost Magnitude adjustment
resolves this.
Test: build/boot Librem 15v3 with Crucial SATA SSD, observe no issues
booting, no ATA-related errors in dmesg on PureOS 10 / kernel 5.8.7
