Add a top level functions to initialize ring groups, and functions
to allocate and free all the rings via HWRM.
A ring group is identified by an index. It consists of Rx or Tx ring id,
completion ring id and a statistics context. Once a ring group is
initialized, use this group index while creating the rings in the ASIC
using the appropriate HWRM API added via earlier patches.
Functions added:
bnxt_free_cp_ring
Calls the HWRM function generic ring free with arguments specific
to a completion ring and sanitizes the host completion structure
bnxt_free_all_hwrm_rings
Frees all the HWRM allocated hardware rings
bnxt_free_all_hwrm_resources
Frees all the resources allocated via the HRM in the hardware
bnxt_alloc_hwrm_rings
Allocates all the HWRM rings needed in the current configuration
This should be the last functionality needed to add start/stop
device operations.

Structures, macros, and functions for working with completion rings

Completion Ring is used by the Ethernet controller to provide the
status of transmitted & received packets, report errors, report
status changes to the host software, and inter-function forwarding
requests. In addition to the generic ring features, a completion ring
can have a statistics context that has statistics periodically DMAed
to host memory, along with a consumer index.
bnxt_handle_async_event() handles completions not related to a specific
transmit or receive ring such as link status changes which arrive on
the default completion ring.
Other physical or virtual functions on the same device may send an HWRM
command forward request. In this case, we will pass it through
unvalidated. In the future, we will be able to have the PF monitor and

Start adding support to use the HWRM API.
Hardware Resource Manager or HWRM in short, is a set of API provided
by the firmware running in the ASIC to manage the various resources.
Initial commit just performs necessary HWRM queries for init, then
fails as before.
Now that struct bnxt is non-zero size, we can set dev_private_size
correctly.
The used HWRM calls so far:
bnxt_hwrm_func_qcaps:
This command returns capabilities of a function.
bnxt_hwrm_ver_get:
This function is called by a driver to determine the HWRM
interface version supported by the HWRM firmware, the
version of HWRM firmware implementation, the name of HWRM
firmware, the versions of other embedded firmwares, and
the names of other embedded firmwares, etc. Gets the
firmware version and interface specifications. Returns
an error if the firmware on the device is not supported
by the driver and ensures the response space is large
enough for the largest possible response.
bnxt_hwrm_queue_qportcfg:
This function is called by a driver to query queue
configuration of a port.
