Subject: staging: use eth_hw_addr_set() for dev->addr_len cases
Patch-mainline: v5.16-rc1
Git-commit: 3928f64b1e473ec951cfbeac42634ff51d4f7f33
References: jsc#PED-1565

Convert all staging drivers from memcpy(... dev->addr_len)
to eth_hw_addr_set():

  @@
  expression dev, np;
  @@
  - memcpy(dev->dev_addr, np, dev->addr_len)
  + eth_hw_addr_set(dev, np)

Manually confirmed these are all etherdevices.
