Enable vcc_sd regulator on boot for NanoPi R2S (#1990)

Browse Source 
NanoPi R2S has the same issue as ROC-RK3328-CC.
With working GPIO, during init the GPIO state s reset.
This causes the sdmmc regulator to shut down, preventing detection.
Removing and replacing the card will allow it to be detected, but that should not be necessary.
Fix this by setting the regulator on at boot.
