Subject: [PATCH] avr32: fix build error in atstk1006_defconfig

fixed the following compile error when use avr32 atstk1006_defconfig:
  drivers/mtd/nand/atmel_nand.c: In function 'pmecc_err_location':
  drivers/mtd/nand/atmel_nand.c:639: error: implicit declaration of function 'writel_relaxed'

which was introduced by commit 1c7b874d33b463 ("mtd: at91: atmel_nand: add Programmable Multibit ECC controller support").
The PMECC for nand flash code uses writel_relaxed(). But in avr32, there is no macro "writel_relaxed" defined. This patch add writex_relaxed macro definitions.
