mmc: dw_mmc: Use mmc_regulator_set_vqmmc in start_signal_voltage_switch
We've introduced a new helper in the MMC core:
mmc_regulator_set_vqmmc(). Let's use this in dw_mmc. Using this new
helper has some advantages:
1. We get the mmc_regulator_set_vqmmc() behavior of trying to match
VQMMC and VMMC when the signal voltage is 3.3V. This ensures max
compatibility.
2. We get rid of a few more warnings when probing unsupported
voltages.
3. We get rid of some non-dw_mmc specific code in dw_mmc.
