mb/purism/librem_skl: drop SataSpeedLimit restriction
SataSpeedLimit was set to 3Gbps to work around issues which are now
known to be the result of incorrect FSP behavior. Since SataPwrOptEnable
is now set at the SoC level and ensures the SIR registers are correctly
programmed, we can re-enable 6Gbps operation without errors.
Test: build/boot Librem 13v2 with both m.2 and 2.5" SATA drives,
check dmesg for errors.
