[PATCH v14 04/11] drivers: add base driver skeleton

[liujie5@linkdatatechnology.com]

From: Jie Liu <liujie5@linkdatatechnology.com>

Initialize the sxe2 PMD skeleton by implementing the PCI probe and
remove functions. This includes the setup and cleanup of a character
device used for control path communication between the user space
and the hardware.

The character device provides an interface for ioctl-based management
operations, supporting device-specific configuration.
