Lo-an Chen e01f07cb92 drm/amd/display: Fix seamless boot sequence
[WHY]
When the system powers up eDP with external monitors in seamless boot
sequence, stutter get enabled before TTU and HUBP registers being
programmed, which resulting in underflow.

[HOW]
Enable TTU in hubp_init.
Change the sequence that do not perpare_bandwidth and optimize_bandwidth
while having seamless boot streams.

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.
