Subject: [PATCH] atmel_lcdfb: Correct fifo size for some products

Remove wrong fifo size definition for some AT91 products.

Due to a misunderstanding of some AT91 datasheets, a fifo size of 2048 (words)
has been introduced by mistake. In fact, all products (AT91/AT32) are sharing
the same fifo size of 512 words.

Can we consider this fix for .30-final ?
