[PATCH] arm64: dts: renesas: r8a779g3: Invert microSD voltage selector on Retronix R-Car V4H Sparrow Hawk EVTB1

Invert the polarity of microSD voltage selector on Retronix R-Car V4H
Sparrow Hawk board. The voltage selector was not populated on prototype
EVTA1 boards, and is implemented slightly different on EVTB1 boards. As
the EVTA1 boards are from a limited run and generally not available,
update the DT to make it compatible with EVTB1 microSD voltage selector.
