Jan Glauber 9e7b9a25e1 mmc: cavium: Prevent crash with incomplete DT ...

In case the DT specifies neither a regulator nor a gpio
for the shared power the driver will crash accessing the regulator.
Prevent the crash by checking the regulator before use.

Use mmc_regulator_get_supply() instead of open coding the same
logic.
