[dpdk-dev] [PATCH v3 19/38] crypto/qat: use generic driver name for PCI registration

[Tomasz Jozwiak <tomaszx.jozwiak@intel.com>]

From: Fiona Trahe <fiona.trahe@intel.com>

The QAT PMD used to register with PCI using the name "crypto_qat".
Keep this name for the driver registered with cryptodev
and use a more generic name "qat" for the PCI registration.
This paves the way for the PCI device to host other services.
