usb: phy: Do not perform phy reset if EUD is enabled

If EUD is enabled and phy reset is performed due to
spoof connect, EUD enumeration fails. Fix this issue
by reading EUD enable register before phy init. Check
the status in msm_hsphy_dpdm_regulator_enable() as well
which also performs phy reset.
