Remove the 'name' member from rte_pci_driver and move to generic
rte_driver.
Most of the PMD drivers were initially using DRIVER_REGISTER_PCI(<name>..)
as well as assigning a name to eth_driver.pci_drv.name member.
In this patch, only the original DRIVER_REGISTER_PCI(<name>..) name has
been populated into the rte_driver.name member - assignments through
eth_driver has been removed.

Simplify crypto and ethdev pci drivers init by using newly introduced
init macros and helpers.
Those drivers then don't need to register as "rte_driver"s anymore.
Exceptions:
- virtio and mlx* use RTE_INIT directly as they have custom initialization
steps.
- VDEV devices are not modified - they continue to use PMD_REGISTER_DRIVER.

PMD_REGISTER_DRIVER.

- Network IXGBE VF driver -> "net_ixgbe_vf"

Modify the PMD_REGISTER_DRIVER macro, adding a name argument to it. The
addition of a name argument creates a token that can be used for subsequent
macros in the creation of unique symbol names to export additional bits of
information for use by the pmdinfogen tool. For example:
PMD_REGISTER_DRIVER(ena_driver, ena);
registers the ena_driver struct as it always did, and creates a symbol
const char this_pmd_name0[] __attribute__((used)) = "ena";
which pmdinfogen can search for and extract. The subsequent macro
DRIVER_REGISTER_PCI_TABLE(ena, ena_pci_id_map);
creates a symbol const char ena_pci_tbl_export[] __attribute__((used)) =
"ena_pci_id_map";
Which allows pmdinfogen to find the pci table of this driver
Using this pattern, we can export arbitrary bits of information.
pmdinfo uses this information to extract hardware support from an object
file and create a json string to make hardware support info discoverable
later.

Following the same approach taken with dev_started field
in rte_eth_dev_data structure, this patch adds two new fields
in it, rx_queue_state and tx_queue_state arrays, which track
which queues have been started and which not.
This is important to avoid trying to start/stop twice a queue,
which will result in undefined behaviour
(which may cause RX/TX disruption).
Mind that only the PMDs which have queue_start/stop functions
have been changed to update this field, as the functions will

memcpy(&dev->data->dev_conf, dev_conf, sizeof(dev->data->dev_conf)) in
rte_eth_dev_configure, which should not happen, and the pointer to
