smsc75xx: replace 0xffff with PHY_INT_SRC_CLEAR_ALL
This patch defines PHY_INT_SRC_CLEAR_ALL to replace the value 0xffff in order to be more self-documenting. This patch should make no functional change, it is purely cosmetic. Signed-off-by: Steve Glendinning <steve.glendinning@shawell.net> Signed-off-by: David S. Miller <davem@davemloft.net>
