Update MT6360 BMC PHY Tx/Rx setting for the compatibility.
Macpaul reported this CtoDP cable attention message cannot be received from
MT6360 TCPC. But actually, attention message really sent from UFP_D
device.
After RD's comment, there may be BMC PHY Tx/Rx setting causes this issue.
Below's the detailed TCPM log and DP attention message didn't received from 6360
TCPCI.

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 Restructured Text 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.
