Make it easier to identify regulator consumers when consumer device
uses more than one supply.

Before:

  regulator                      ena use open bypass voltage current min     max
 -----------------------------------------------------------------------------------
  regulator-dummy                  1   0    2      0     0mV     0mA 0mV     0mV
     1-0010                                                          0mV     0mV
     1-0010                                                          0mV     0mV

After:

  regulator                      ena use open bypass voltage current min     max
 -----------------------------------------------------------------------------------
  regulator-dummy                  1   0    2      0     0mV     0mA 0mV     0mV
     1-0010-vccio                                                    0mV     0mV
     1-0010-vcc33                                                    0mV     0mV
