[PATCH] phy: qualcomm: phy-qcom-eusb2-repeater: Fix SMB Power leakage issue

[Krishna Kurapati]

On Glymur, it is observed that although the exit call is done, there is a
power leakage seen on SMB2370 charger (which embeds the eUSB2 module as
well). As per recommendation of HW team, disable the repeater during the
exit call to prevent this power leakage.
