enc28j60: Convert HW related printk() to dev_printk()

Browse Source 
The debug prints of hardware status and operations will look better
if SPI device name is printed. The benefit of that is a possibility
to distinguish the actual hardware when more than one is installed
on the system.

Convert appropriate printk(KERN_DEBUG) to dev_print(KERN_DEBUG, &spi->dev).
