[RFC 2/3] mmc: sdhci: add host_ops->voltage_switch callback for all other voltages

Currently, the sdhci_do_start_signal_voltage_switch() function invokes controller specific voltage switch configuration only for 1.8v usecase; but it is required for others as well. For example, in case of PXA1928 SDH controller, we need to set different configuration for 3.3, 1.8 and 1.2 volt
