When 'ionic_cmb' is set to '1', queue memory will be allocated from
the device's onboard memory (Controller Memory Buffer). In some
configurations, this will dramatically reduce packet latency and
increase PPS.
Add the WC_ACTIVATE flag to the PCI driver flags.
Write combining must be enabled to achieve the maximum PPS.
When the queue is in the CMB, descriptors cannot be prefetched.

For future support of virtual devices, move the PCI code to its own
file. Create a new device interface, struct ionic_dev_intf, to plug
in to common code.

The pci bus interface is for drivers only.
Mark as internal and move the header in the driver headers list.
While at it, cleanup the code:
- fix indentation,
- remove unneeded reference to bus specific singleton object,
- remove unneeded list head structure type,
- reorder the definitions and macro manipulating the bus singleton object,
- remove inclusion of rte_bus.h and fix the code that relied on implicit
inclusion,

The adminq is the only caller of ionic_q_service(), so absorb it
into ionic_adminq_service().
Move all of the adminq code together into ionic_main.c.
Staticize a few things.

Expose ionic_opcode_to_str() so it can be used for dev cmds, too.
Store the device name in struct adapter.
Switch to memcpy() to work around gcc false positives.
