drivers/net/ks*: Use netdev_<level>, netif_<level> and pr_<level>

I'm not sure this is correct.

It changes logging macros from:
	dev_<level>(&ks->spidev->dev,
to
	netdev_<level>(ks->netdev,

Comments?

Use netdev_<level>
Use netif_<level>
Use pr_<level>
Add #define pr_fmt(fmt) KBUILD_MODNAME ": " fmt
Add missing line to message in ks8851_remove
Change kmalloc/memset(,0) to kzalloc
Remove ks_<level> macros
Consolidation code into set_media_state
