8390 : Replace ei_debug with msg_enable/NETIF_MSG_* feature
Removed the shared ei_debug variable. Replaced it by adding u32 msg_enable to the private struct ei_device. Now each 8390 ethernet instance has a per-device logging variable. Changed older style printk() calls to more canonical forms. Tested on: ne, ne2k-pci, smc-ultra, and wd hardware. V4.0 - Substituted pr_info() and pr_debug() for printk() KERN_INFO and KERN_DEBUG V3.0 - Checked for cases where pr_cont() was most appropriate choice. - Changed module parameter from 'debug' to 'msg_enable' because debug was no longer the best description. V2.0 - Changed netif_msg_(drv|probe|ifdown|rx_err|tx_err|tx_queued|intr|rx_status|hw) to netif_(dbg|info|warn|err) where possible.
