Need generic definition for readl_relaxed(), like other architectures
have done. Or can not pass compiling with allmodconfig, the related
error:

    CC [M]  drivers/message/fusion/mptbase.o
  drivers/message/fusion/mptbase.c: In function 'mpt_send_handshake_request':
  drivers/message/fusion/mptbase.c:1224: error: implicit declaration of function 'readl_relaxed'
