I want to get permanent MAC address when the interface is down. And I think
it is more convenient to get statistics in the down state by 'ethtool -S'.
But current all of the ethool command return -EBUSY.

I don't think we should check that the network interface is up in '.begin',
which will cause that all the ethtool commands can't be used when the
network interface is down. If some ethtool commands can only be used in the
up state, check it in the corresponding ethool OPS function is better.
This is too rude and unreasonable.

Compile-tested on arm64. Tested on an arm64 system with an on-board
STMMAC chip.

Changes v7 ... v8:
- Optimize commit description information, optimization parameters of
  pm_runtime function.

Changes v6 ... v7:
- fix arg type error of 'dev' to 'priv->device'.

Changes v5 ... v6:
- The 4.19.90 kernel not support pm_runtime, so implemente '.begin' and
  '.complete' again. Add return value check of pm_runtime function.

Changes v4 ... v5:
- test the '.begin' will return -13 error on my machine based on 4.19.90
  kernel. The platform driver does not supported pm_runtime. So remove the
  implementation of '.begin' and '.complete'.

Changes v3 ... v4:
- implement '.complete' ethtool OPS.

Changes v2 ... v3:
- add linux/pm_runtime.h head file.

Changes v1 ... v2:
- fix spell error of dev.
