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).

README

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
