rt2x00: add queue_init callback to rt2x00_ops
The driver uses static data structures for initializing
specific fields of a given data queue. These static
queue data descriptor structures are containing values
which related to a given chipset.
Even though the values are chip specific, the actual
selection of the used structure is based on device
specific vendor/product identifiers. This approach works,
but it is not always reliable. Sometimes the vendor and/or
device IDs of the PCI and USB devices contains improper
values which makes it impossible to select the correct
structure for such devices.
The patch adds a new callback to tr2x00_ops which
is called after the chipset detection is finished.
This allows the drivers to do dynamic initialization
of the data_queue structure for a given queue based
on the actual chipset.
After each driver implements the queue_init callback,
the data_queue_desc structure will be removed.
