sstfb: fix pixclock setting on Voodoo 1/2 cards

From: Ondrej Zajicek <[email protected]>

Pixclock setting in sstfb didn't work with my Voodoo 2 card with ICS 5342 DAC (this DAC requires two consecutive writes to one of its registers to program pixclock - maybe first write merged with second).

This patch fixes bug with pixclock setting. It is against 2.6.21-rc1 .

These three patches look 2.6.21ish to me?

They are safe for 2.6.21.
