Subject: pm2fb: Permedia 2V initialization fixes
From: Krzysztof Helt <krzysztof.h1@xxxxx>
This patch:
- initializes correctly the Permedia2V chip if it is not initialized by BIOS
- puts back clock frequency for the ELSA WINNER board to 100kHz
- fixes returned error values from setcolreg() function
- uses more general classes for PCI ids
