[PATCH] fbdev: Add generic ddc read functionality
Adds functionality to read the EDID information over the DDC bus in a generic
way. This code is based on the DDC implementation in the radeon driver.
[adaplas]
- separate from fbmon.c and place in new file fb_ddc.c
- remove dependency to CONFIG_I2C and CONFIG_I2C_ALGOBIT, otherwise, feature
will not compile if i2c support is compiled as a module
- feature is selectable only by drivers needing it. It must have a
'select FB_DDC if xxx' in Kconfig
- change printk's to dev_*, the i2c people prefers it
