Subject: [PATCH 03/14] net: ks8851: Pass device pointer into ks8851_init_mac()

Since the driver probe function already has a struct device *dev pointer,
pass it as a parameter to ks8851_init_mac() to avoid fishing it out via
ks->spidev. This is the only reference to spidev in the function, so get
rid of it. This is done in preparation for unifying the KS8851 SPI and
parallel drivers.

No functional change.
