support in the MSCC PHY driver.

  mscc_macsec.c:393:42: warning: cast from restricted sci_t
  mscc_macsec.c:395:42: warning: restricted sci_t degrades to integer
  mscc_macsec.c:402:42: warning: restricted __be16 degrades to integer
  mscc_macsec.c:608:34: warning: cast from restricted sci_t
  mscc_macsec.c:610:34: warning: restricted sci_t degrades to integer
