Jesse Buhagiar 6c1a549057 PATAChannel: Alert user when no PCI device is found ...

This helps aid debugging of issues such as #695, where the bridge chip
that controls IDE is NOT a PIIX3/4 compatible controller. Instead of
just hanging when the DMA registers can't be accessed, the system will
inform the user that no valid IDE controller has been found. In this
case, the system will not attempt to initialise the DMA registers and
instead use PIO mode.
