Implement support for PTP clock on Wangxun NICs.

Changes in v6:
- Link to v5: https://lore.kernel.org/all/[e-mail]/
- Add "depends on PTP_1588_CLOCK_OPTIONAL" in Kconfig to fix build
  errors

Changes in v5:
- Link to v4: https://lore.kernel.org/all/[e-mail]/
- Use reading template for timecounter_cyc2time()
- Move the same piece of codes to the functions
- Fix read sequence for time registers
- Remove skb_shared_hwtstamps zero out
- Pass duty cycle for the pulse width

Changes in v4:
- Link to v3: https://lore.kernel.org/all/[e-mail]/
- 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/[e-mail]/
- 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/[e-mail]/
- 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
- Rename function wx_ptp_start_cyclecounter()
- Keep the register names consistent between comments and code

## Form letter - net-next-closed

The merge window for v6.14 has begun. Therefore net-next is closed
for new drivers, features, code refactoring and optimizations.
We are currently accepting bug fixes only.

Please repost when net-next reopens after Feb 3rd.

RFC patches sent for review only are obviously welcome at any time.
