Subject: net: cpsw: fix misplaced break statements.

Having the breaks too far to the left makes parsing the dense switch/case
block unnecessarily harder.

Subject: net: cpsw: remove two unused global functions

The funtions, cpsw_ale_flush and cpsw_ale_set_ageout, have never been used
since they were first introduced.  This patch removes the dead code.

Subject: net: cpsw: remove redundant calls enabling dma interrupts.

The function, cpsw_intr_enable, already calls cpdma_ctlr_int_ctrl.  There
is no need to enable the dma interrupts twice.  This patch removes the
extra call.
