Implement support for PTP clock on Wangxun NICs.

Changes in v4:
- Link to v3: https://lore.kernel.org/all/20250110031716.2120642-1-jiawenwu@trustnetic.com/
- Add tx_hwtstamp_errors to record errors of DMA mapping
- Remove flag bits clear for default case in setting TS mode
- Change to use seqlock_t hw_tc_lock
- Add ptp_schedule_worker in wx_ptp_reset()
- Remove perout index check
- Refactor the same code into a function

Changes in v3:
- Link to v2: https://lore.kernel.org/all/20250106084506.2042912-1-jiawenwu@trustnetic.com/
- Clean up messy patches
- Return delay value in wx_ptp_do_aux_work()
- Remove dev_warn()
- Implement ethtool get_ts_stats
- Support PTP_CLK_REQ_PEROUT instead of PTP_CLK_REQ_PPS
- Change to start polling Tx timestamp once descriptor done bit is set

Changes in v2:
- Link to v1: https://lore.kernel.org/all/20250102103026.1982137-1-jiawenwu@trustnetic.com/
- Fix build warning
- Convert to .ndo_hwtstamp_get and .ndo_hwtstamp_set
- Remove needless timestamp flags
- Use .do_aux_work instead of driver service task
- Use the better error code
