at91sam9m10g45ek: add board revision support
we use the board revision to specify to the linux kernel the type of lcd
we use. So we can have only one machine for those 3 boards:
- sam9m10-ekes (LG)
- sam9g45-ekes (LG)
- sam9m10g45-ek (Truly)
today we support 2 lcds model:
- LG philips LB043WQ1
- Truly TFT1N4633-E
by default we select the Truly as the sam9m10g45-ek is the most common board
