The phy framework requests an optional "phy" regulator. If it does
not find one, it returns -EPROBE_DEFER. In the case of non-DT based boot
for the omap138-lcdk board, this would prevent the usb11 phy to probe
correctly and ohci would not enumerate.

By calling "regulator_has_full_constraints", An error would be returned
instead of DEFER for the "optional" regulator, and the probe of
the phy driver can continue normally without a regulator.
