This has some very long delays with interrupts off from the
spin_lock_irqsave. I guess thats hardly #1 priority though nor a killer.

This doesn't do quite what you might think - if the device is mmio mapped
then the write can be posted so the mdelay(2) may not be 2mS. I guess if
the old driver didn't do it then it was already plenty long enough...
