Subject: [PATCH] NFC: nxp-nci: Include unaligned.h instead of access_ok.h

Directly including access_ok.h can result in the following compile errors
if an architecture such as ia64 does not support direct unaligned accesses.

include/linux/unaligned/access_ok.h:7:19: error:
	redefinition of 'get_unaligned_le16'
include/linux/unaligned/le_struct.h:6:19: note:
	previous definition of 'get_unaligned_le16' was here
include/linux/unaligned/access_ok.h:12:19: error:
	redefinition of 'get_unaligned_le32'
include/linux/unaligned/le_struct.h:11:19: note:
	previous definition of 'get_unaligned_le32' was here

Include asm/unaligned.h instead and let the architecture decide which
access functions to use.
