regulator: stw481x-vmmc: fix ages old enable error
commit 295070e9aa015abb9b92cccfbb1e43954e938133 upstream.
The regulator has never been properly enabled, it has been
dormant all the time. It's strange that MMC was working
at all, but it likely worked by the signals going through
the levelshifter and reaching the card anyways.
