[dpdk-dev] [PATCH v5 2/9] eal: introduce RTE common initialization level

[Parav Pandit]

Currently mlx5_common uses CLASS priority to initialize
common code before initializing the PMD.
However mlx5_common is not really a class, it is the pre-initialization
code needed for the PMDs.

In subsequent patch a needed initialization sequence is:
(a) Initialize bus (say pci)
(b) Initialize common code of a driver (mlx5_common)
(c) Register mlx5 class PMDs (mlx5 net, mlx5 vdpa)
Information registered by these PMDs is used by mlx5_bus_pci PMD.
This mlx5 class PMDs should not confused with rte_class.
(d) Register mlx5 PCI bus PMD

Hence, introduce a new RTE priority level RTE_PRIO_COMMON which
can be used for common initialization and RTE_PRIO_CLASS by mlx5 PMDs
for class driver initialization.
