Today we mix pdata and drivers data in the struct atmel_lcdfb_info
Fix it and introduce a new struct atmel_lcdfb_pdata for platform data only

I think lcdcon_pol_negative should be part of pdata, because it really
depends on how the PWM is wired on the board.

maybe but no one mainline use it on any pdata for non-dt boars
so I did not want to expose it
