mtd: nand: atmel: Fix get_sectorsize() function

Browse Source 
commit 2b1b1b4ac7 upstream.

get_sectorsize() was not using the appropriate macro to extract the
ECC sector size from the config cache, which led to buggy ECC when
using 1024 byte sectors.

Fixes: f88fc122cc ("mtd: nand: Cleanup/rework the atmel_nand driver")
