Subject[PATCH] regulator: use consumer->supply_name in debugfs/regulator_summary
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
