The RFE interrupt is enabled for the r8a7790 but isn't handled,
resulting in the interrupts core noticing unhandled interrupts, and
eventually disabling the ethernet IRQ.

Fix it by adding RFE to the bitmask of error interrupts to be handled
for r8a7790.

So, Simon hasn't synced his patch to my late bug fix in 3.10... Did this
patch help you with your NFS boot issue, Laurent?
Yes, it fixes the "disabling interrupt, nobody cared" problem. I still have
intermittent NFS issues, but at least I can now boot.
    I was somewhat thrown off by the Rx FIFO overflow messages appearing before
the "nobody cared", so I thought that must be another unhandled interrupt.

WBR, Sergei
