This series adds initial support for the ZTE DingHai Ethernet controller,
a high-performance PCIe Ethernet device supporting SR-IOV, hardware
offloading, and advanced virtualization features.

Changes from v1 (addressing feedback from AndrewLunn):
- Update copyright years to 2022-2026
- Remove DRV_VERSION, MODULE_VERSION and related boilerplate
- Fix MODULE_AUTHOR to use person with email address
- Use module_pci_driver() instead of manual init/exit
- Remove empty suspend/resume callbacks
- Replace char priv[] flexible array with void *priv + kzalloc
- Switch logging from printk wrappers to dev_*() based macros
- Remove dh_helper.h and dh_log.c, simplify to dh_log.h only
- Fix variable declaration ordering (reverse Christmas tree)
- Remove unnecessary NULL check in remove and pf_dev=NULL in probe
- Fix indentation and remove unnecessary type casts
- Use kernel idiomatic "if (ret)" style

This patch series is organized as follows:
- Patch 1: Add basic driver framework (Kconfig/Makefile, probe/remove skeleton)
- Patch 2: Add logging infrastructure using kernel standard dev_* macros
- Patch 3: Add hardware register access and PCI capability scanning

This is the initial submission and only includes the PF (Physical Function)
driver. The VF (Virtual Function) driver will be submitted separately.

capability scanning
