viafb: eliminate modetable dependancy of LCD modesetting
This patch removes the need for knowing the modetable structure within the LCD modesetting function. The magic 60Hz refresh rate was already there as always the first entry for a resolution was choosen based on the ascending refresh rate ordering in the modetable. For all but one this is at least 60Hz, if only higher frequencies available we choose those like the code before did. The exception is OLPC but that resolution has only one frequency so we get the same behaviour there as well. Signed-off-by: Florian Tobias Schandinat <FlorianSchandinat@gmx.de>
