Subject: [PATCH] NFC: nfcmrvl: Include unaligned.h instead of access_ok.h

Including linux/unaligned/access_ok.h causes the allmodconfig build on
ia64 (and maybe others) to fail with the following warnings:

include/linux/unaligned/access_ok.h:7:19: error: redefinition of 'get_unaligned_le16'
include/linux/unaligned/access_ok.h:12:19: error: redefinition of 'get_unaligned_le32'
include/linux/unaligned/access_ok.h:17:19: error: redefinition of 'get_unaligned_le64'
include/linux/unaligned/access_ok.h:22:19: error: redefinition of 'get_unaligned_be16'
include/linux/unaligned/access_ok.h:27:19: error: redefinition of 'get_unaligned_be32'
include/linux/unaligned/access_ok.h:32:19: error: redefinition of 'get_unaligned_be64'
include/linux/unaligned/access_ok.h:37:20: error: redefinition of 'put_unaligned_le16'
include/linux/unaligned/access_ok.h:42:20: error: redefinition of 'put_unaligned_le32'
include/linux/unaligned/access_ok.h:42:20: error: redefinition of 'put_unaligned_le64'
include/linux/unaligned/access_ok.h:42:20: error: redefinition of 'put_unaligned_be16'
include/linux/unaligned/access_ok.h:42:20: error: redefinition of 'put_unaligned_be32'
include/linux/unaligned/access_ok.h:42:20: error: redefinition of 'put_unaligned_be64'

Fix these by including asm/unaligned.h instead and leave it up to the
architecture to decide how to implement unaligned accesses.
