[PATCH v3 3/4] phy: qcom: phy-qcom-snps-eusb2: Add missing write from init sequence

[Luca Weiss]

As per a commit from Qualcomm's downstream 6.1 kernel[0], the init
sequence is missing setting the CMN_CTRL_OVERRIDE_EN bit back to 0 at
the end, as per the 'latest' HPG revision (as of November 2023).
