Consolidate flow stat related structs for performance improvement.
The intention of this patch is to reduce the size struct bnxt which
had grown because of recent changes and was impacting performance.

This patch allows to display flow stats in extended stats.
To do this, DMA-able memory is registered with the FW during device
initialization. Then the driver uses an alarm thread to query the
per flow stats using the HWRM_CFA_COUNTER_QSTATS HWRM command at
regular intervals and stores it locally which will be displayed
when the application queries the xstats.
The DMA-able memory is unregistered during driver cleanup.
This functionality can be enabled using the flow-xstat devarg and
will be disabled by default. The intention behind this is to allow
stats to be displayed for all the flows in one shot instead of
querying one at a time.

Refactor init and uninit functions so that the driver can fail
the eth_dev_ops callbacks and accessing Tx and Rx queues
when device is in reset or in error state.
Transmit and receive queues are freed during reset cleanup and
reallocated during recovery. So we block all data path handling
in this state. The eth_dev dev_started field is updated depending
on the status of the device.

Certain SKUs of NIC can support features like NPAR, Multi Host PFs per
port. We need to check for such features in order to restrict certain
HWRM commands from being sent to the FW.
For the single PF per port model, allow commands like hwrm_port_phy_cfg
from the PF driver. In NPAR and MH environments with multiple PFs per
port, we should not allow HWRM commands like hwrm_port_phy_cfg to be
sent to the FW.
This patch takes care of that.

The stats_get dev op API doesn't include return value, so PMD cannot
return an error in case of failure at stats getting process time.
Since PCI devices can be removed and there is a time between the
physical removal to the RMV interrupt, the user may get invalid stats
without any indication.
This patch changes the stats_get API return value to be int instead of
void.
