This removes the internal ide-cd buffer and falls back to read-ahead block layer
capabilities. Thorough testing (cd burning, dvd read, raw read) gives with the
bufferless mode marginally better performance in addition to simplified code.

* Add IDE_HFLAG_QD_2ND_PORT host flag to indicate the need of skipping
first ide_hwifs[] slot for the second port of QD65xx controller.
* Handle this new host flag in ide_find_port_slot().
* Convert legacy VLB host drivers to use ide_find_port().
While at it:
* Fix couple of printk()-s in qd65xx host driver to not use hwif->name.

This function didn't actually check if a given BAR is in I/O space because of
using the bogus PCI_BASE_ADDRESS_IO_MASK (which equals ~3) to test the resource
flags instead of IORESOURCE_IO -- fix this, make ide_hwif_configure() check the
results failing if necessary, and move the printk() call to the failure path.

conflicting locks") changed fs/lockd/svclock.c to call
__locks_copy_lock() instead of locks_copy_lock(), but lockd can be built
as a module and __locks_copy_lock() is not exported, which causes a
build error
