viafb: rework the I2C support in the VIA framebuffer driver
This patch changes the way how the various I2C busses are used internally
inside the viafb driver: Previosuly, only a single i2c_adapter was created,
even though two different hardware I2C busses are accessed: A structure member
in a global variable was modified to indicate the bus to be used.
Now, all existing hardware busses are registered with the i2c core, and the
viafb_i2c_{read,write}byte[s]() function take the adapter number as function
call parameter, rather than referring to the global structure member.
[jc: even more painful merge with mainline changes ->2.6.34]
