atmel_lcdfb: correct fifo size for some products

commit 53b7479bbdaedcc7846c66fd608fe66f1b5aa35b upstream.

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.
