m68k: macmace fixes
Fix a race condition in the transmit code, where the dma interrupt could update the free tx buffer count concurrently and wedge the tx queue. Fix the misuse of the rx frame status and rx frame length registers: no more "fifo overrun" errors caused by the OFLOW bit being tested in the frame length register (instead of the status register), and no more missed packets due to incorrect length taken from status register (instead of the frame length register). Fix a panic (skb_over_panic BUG) caused by allocating and then copying an incoming packet while the packet length register was changing. Cut-and-paste the reset code from the powermac mace driver (mace.c), so the NIC functions when MacOS does not initialise it (important for anyone wanting to use the Emile boot loader). Cut-and-paste the error counting and timeout recovery code from mace.c. Fix over allocation of rx buffer memory (it's page order, not page count). Converted to driver model. Converted to DMA API. Since I've run out of ways to make it fail, and since it performs well now, promote the driver from EXPERIMENTAL status. Tested on both quadra 840av and 660av.
