[PATCH v2] ARM: imx: armadillo5x0: Fix illegal register access

[Fabio Estevam]

From: Fabio Estevam <fabio.estevam at freescale.com>

commit 0c8bad6a(Armadillo 500 add NAND flash device support (resend).)
introduced an incorrect access to MXC_CCM_RCSR.

MXC_CCM_RCSR is an offset and in order to properly access this register, 
the mx3_ccm_base needs to be passed, otherwise an illegal access is done.
