Restore Digital Outpur Register (DOR) for enhanced controller after reset.

Assume floppy disk is not inserted when we have exhausted retries. This

significantly reduces booting time when there is broken floppy disk drive, controller, cable, BIOS, etc. When the floppy controller interface is correctly implemented, disk change signal (DSKCHG) is reflected in the Digital Input Register (DIR) at 0x3f7. However, there are many cases that the signal is unusable. Moreover, some BIOS does not reserve the port at all. In those cases, the register may not function.

Enhanced floppy controllers have Data Rate Select Register (DSR) at 0x3f4.

Use it to reset controller and to select data rate. According to Intel 80277AA datasheet, software reset behaves the same as DOR reset except that it is self clearing. National Semiconductor PC8477B datasheet says the same. As a side effect, we no longer use Configuration Control Register (CCR) at 0x3f7 for these controllers, which is often missing in modern hardware.

mutex. - Don't use callout_drain() to stop the toffhandle callout while holding the fdc mutex (this could deadlock) in functions called from softclock (callouts aren't allowed to do voluntary sleeps). Instead, use callout_stop(). Note that since we hold the associated mutex and are now using callout_init_mtx(), callout_stop() is just as effective as callout_drain(). (Though callout_drain() is still needed in detach to make sure softclock isn't contesting on our mutex before we destroy the mutex.) - Remove unused callout 'tohandle' from softc. MFC after: 1 week
