<content type='text'>
[WHY &amp; HOW]
PB9 bit 5 was added to signal PQ EOTF in AMD vendor specific infoframe.
This change sets it when appropriate.

<id>urn:sha1:43693e859b328db6017e51e93b4da36fe64d6e47</id>
<content type='text'>
[WHY]
FreeSync spec requires PB8 and PB12 to be set to nominal
refresh rate regardless of fixed rate or variable

[HOW]
Removed the condition that checks and overwrites max refresh rate
and set PB8/PB12 to be set to max refresh rate always

<content type='text'>
There are two places in apply_below_the_range() where it's possible for
a divide by zero error to occur. So, to fix this make sure the divisor
is non-zero before attempting the computation in both cases.

<id>urn:sha1:da55037afde24d74a1a3f26e4d314f897f3432b4</id>
<content type='text'>
Why:
Some EDIDs report a minimum refresh rate lower than what HW can support

How:
Add a check to calculate minimum supported refresh rate with current timing
and use that as the minimum if a lower one is passed in
