mmc: dw_mmc: Keep vqmmc-supply enable count in balanceWIP/2023-08-11-keep-fixed-gpio-regulator-count-in-balance
With the commit 4fcba5d556b4 ("regulator: implement basic reference
counter"), keeping regulator enablement in balance become more important.
Disable vqmmc-supply before signal voltage is changed to keep regulator
enable counter in balance.
