PATCH 1/1 Cirrus Logic framebuffer I2C support

Hi,

The attached patch adds I2C support to Cirrus Logic framebuffer driver. Only "I2C adapter" is supported, it's not used for DDC purposes. Tested with an old Intel R440LX machine against ST M24512 I2C EEPROM connected to VGA DDC signals.

Currently works with "Alpine" chips only (CL-GD543x and 544x).

I've done it for my tests but don't know why should I keep it private.
