Florian Tobias Schandinat c91faa6169 viafb: remove unused max_hres/vres
This patch removes the max_hres and max_vres which are not used at
the moment. In general they could be useful but it would be better
to get them via any standard EDID implementation and not the buggy
incomplete one currently used which is also removed as far as
possible.

Florian Tobias Schandinat 0523656eed viafb: kill crt_setting_information
As the iga path is the only remaining information which is also
handled by the active devices there is no reason to keep it.

Florian Tobias Schandinat 726abbc795 viafb: refresh rate bug collection
This patch fixes multiple issues with the handling of refresh rates
especially for multi-display setups. If you experienced problems
with wrong refresh rates this patch might fix them.

Florian Tobias Schandinat d90108765b viafb: strip some structures
This patch removes some write-only variables from the device management
structures. Just a small cleanup.

Florian Tobias Schandinat dbf85f2326 viafb: kill lcd_panel_id
This patch removes all internal uses of another mostly artificial
value. It does duplicate the information of the maximum resolution and
it is not flexible as only a few resolutions exist. Hence it is better
to remove it and clean the mess up.
No runtime change expected.

Florian Tobias Schandinat 51f4332bb5 viafb: add initial VX900 support
This patch adds basic support for the new VX900 IGP. Almost everything
that was implemented for other IGPs is expected to work also on VX900
after this patch. The only known issue is that on the CRT output mode
setting does not always work.
It is clear that the possibility for regressions is zero.

A big thanks to VIA Technologies for making this possible and
supporting this work.

Florian Tobias Schandinat cc3fd679a3 viafb: simplify lcd size "detection"
viafb: simplify lcd size "detection"

Remove all occurences of get_lcd_size_method as only the values
GET_LCD_SIZE_BY_VGA_BIOS and GET_LCD_SIZE_BY_USER_SETTING were used
which had the identical code so there is no need to make things look
more complicated than they actually are.
Just a bit of of cleanup, really no regressions expected.

Florian Tobias Schandinat c5f06f5cdd viafb: some dvi cleanup
Remove some unused variables, move some dvi code around and store the
detected maximum resolution for later use.  The vertical resolution is
handled as the old code did it but I hope it can be read from the hardware
some day.

No runtime change expected.

Florian Tobias Schandinat 9b24b00c36 viafb: remove the remaining VIA_RES_* uses
Remove the rest of the VIA_RES_* use cases.  Obviously this was no longer
useful.  Keep the related infrastructure/functions for later use.

No runtime impact expected.
