pinctrl: sunxi: Fix and simplify pin bank regulator handling
The new per-pin-bank regulator handling code in the sunxi pinctrl driver
has mismatched conditions for enabling and disabling the regulator: it
is enabled each time a pin is requested, but only disabled when the
pin-bank's reference count reaches zero.
Since we are doing reference counting already, there's no need to enable
the regulator each time a pin is requested. Instead we can just do it
for the first requested pin of each pin-bank. Thus we can reverse the
test and bail out early if it's not the first occurrence.
