mmc: rtsx: remove driving adjustment
Several new models of readers use different way to select driving
capability (a necessary adjustment along with voltage change). Removing
this from device-independent rtsx_pci_sdmmc module. It will be implemented
in device-depend calls encapsulated by rtsx_pci_switch_output_voltage().
