Luca Weiss 31bc94de76 phy: qualcomm: phy-qcom-eusb2-repeater: Don't zero-out registers 
Zeroing out registers does not happen in the downstream kernel, and will
"tune" the repeater in surely unexpected ways since most registers don't
have a reset value of 0x0.

Stop doing that and instead just set the registers that are in the init
sequence (though long term I don't think there's actually PMIC-specific
init sequences, there's board specific tuning, but that's a story for
another day).
