Failed to set resolutions with 2.5k@90Hz panels

[AceLan Kao]

[Impact]
Failed to set resolutions with new 2.5k@90Hz panels, the reported resolutions from xrandr are all invalid and got blank screen.

[Fix]
Below commit re-calculate clock and refresh rate fixes this issue.
https://gitlab.freedesktop.org/xorg/xserver/-/merge_requests/993

[Test]
Verified on 2.5k@90Hz panel laptops and my laptop 1920x1080@60Hz
Will be tested in proposed for wider range.

[Where problems could occur]
Not sure if the re-calculated clock and refresh rate works for all different panels, need to verify it wider in proposed.

The patches look good but sadly... there has been an xorg-server security update yesterday that used the version numbers of the uploads in the queue. Please rebase on the latest security versions and re-upload!
