Commit 941432d00768 ("arm64: dts: allwinner: Drop non-removable from
SoPine/LTS SD card") enabled the card detect GPIO for the SOPine module,
along the way with the Pine64-LTS, which share the same base .dtsi.
However while both boards indeed have a working CD GPIO on PF6, the
polarity is different: the SOPine modules uses a "push-pull" socket,
which has an active-high switch, while the Pine64-LTS use the more
traditional push-push socket and the common active-low switch.
Fix the polarity in the sopine.dtsi, and overwrite it in the LTS
board .dts, to make the SD card work again on systems using SOPine
modules.
