[PATCH 5/5] sh_eth: make sh_eth_tsu_{read|write}_entry() prototypes symmetric

[Sergei Shtylyov <sergei.shtylyov@cogentembedded.com>]

sh_eth_tsu_read_entry() is still asymmetric with sh_eth_tsu_write_entry()
WRT their prototypes -- make them symmetric by passing to the former a TSU
register offset instead of its address and also adding the (now necessary)
'ndev' parameter...
