[Nobuhiro Iwamatsu]

Handling of IRQ of the SH7763/SH7764 CPU which sh_eth supported was

The sh changes this depends on for the CPU subtypes are merged upstream
now, so this can go through either tree. As there is nothing really
netdev specific about this, I suppose the easiest is to just roll both of
these in to the sh tree.

Oh, nevermind, I see these were merged already through the net tree..

I should have reported that these were taken in.
I will report it from the next time.
