[PATCH 04/20] pm2fb: memclock setting corrections

["Antonino A. Daplas" <adaplas@gmail.com>]

From: Krzysztof Helt <krzysztof.h1@wp.pl>

This patch disables a memory clock setting if a board has been
initialized by BIOS. This allows using the memory clock set by
manufacturer of the board.
This patch also sets default clock for 3dlabs Permedia 2V
reference board's clock to 75MHz (BIOS setting for EONtronic
Permedia 2Vboard), because the default 83MHz can be too high.
