sh_eth: add wake-on-lan support via magic packet

This series adds support for Wake-on-Lan using Magic Packet for a few
models of the sh_eth driver. Patch 1/6 fix a naming error, patch 2/6
adds generic support to control and support WoL while patches 3/6 - 6/6
enable different models.

Based ontop of net-next master.

Changes since v2.
- Fix bookkeeping for "active_count" and "event_count" reported in
  /sys/kernel/debug/wakeup_sources. Thanks Geert for noticing this.
- Add new patch 1/6 which corrects the name of ECMR_MPDE bit, suggested
  by Sergei.
- s/sh7743/sh7734/ in patch 5/6. Thanks Geert for spotting this.
- Spelling improvements suggested by Sergei and Geert.
- Add Tested-by to 3/6 and 4/6.

Changes since v1.
- Split generic WoL functionality and device enablement to different
  patches.
- Enable more devices then Gen2 after feedback from Geert and
  datasheets.
- Do not set mdp->irq_enabled = false and remove specific MagicPacket
  interrupt clearing, instead let sh_eth_error() clear the interrupt as
  for other EMAC interrupts, thanks Sergei for the suggestion.
- Use the original return logic in sh_eth_resume().
- Moved sh_eth_private variable *clk to top of data structure  to avoid
  possible gaps due to alignment restrictions.
- Make wol_enabled in sh_eth_private part of the already existing
  bitfield instead of a bool.
- Do not initiate mdp->wol_enabled to 0, the struct is kzalloc'ed so
  it's already set to 0.
