ARM: at91/avr32/atmel_lcdfb: add platform device-id table
Add platform device-id table in order to identify the controller and determine its configuration. The currently used configuration parameters are: have_alt_pixclock - SOC uses an alternate pixel-clock calculation formula (at91sam9g45 non-ES) have_hozval - SOC has a HOZVAL field in LCDFRMCFG which is used to determine the linesize for STN displays (at91sam9261, at921sam9g10 and at32ap) have_intensity_bit - SOC uses IBGR:555 rather than BGR:565 16-bit pixel layout (at91sam9261, at91sam9263 and at91sam9rl) This allows us to remove all the remaining uses of cpu_is macros from the driver. Tested on at91sam9263 and at91sam9g45, compile-tested for other AT91-SOCs, and untested for AVR32.
