This patch adds support suspend/resume for R-Car controllers.
The controllers need firmware downloading and the current code has
such process only when probe timing. After suspend the system and
the power of controller down, the driver needs to re-download the firmware
in resume timing. This patch
This patch sets resume_quirk() for R-Car controllers to re-download
the firmware in resume timing. Otherwise, if the controller's power
is down in suspend timing, the firmware in the controller goes away,
and then the controller doesn't work after resume.

This patch enables the clk in resume timing when device_may_wakeup()

The ethtool api {get|set}_settings is deprecated.
We move this driver to new api {get|set}_link_ksettings.
As I don't have the hardware, I'd be very pleased if
someone may test this patch.

The patch fixes that. By the way it rearranges error lables just to improve
readability of quite complex dependencies in error handling code.
