mmc: core: add helpers mmc_regulator_enable/disable_vqmmc
[ Upstream commit 8d91f3f8ae57e6292142ca89f322e90fa0d6ac02 ]
There's a number of drivers (e.g. dw_mmc, meson-gx, mmci, sunxi) using
the same mechanism and a private flag vqmmc_enabled to deal with
enabling/disabling the vqmmc regulator.
Move this to the core and create new helpers mmc_regulator_enable_vqmmc
and mmc_regulator_disable_vqmmc.
