Sync wm(4) up to if_wm.c rev. 1.537:
- Set WMREG_KABGTXD not in wm_init_locked() but in wm_reset().
- If a legacy interrupt is a spurious interrupt, don't print debug
  message.
- Don't print the Image Unique ID if an NVM is iNVM (i210 and I211).
- Fix a bug that a RAL was written at incorrect address when the index
  number is more than 16 on 82544 and newer.
- The layout of RAL on PCH* are different from others. Fix it.
- Flush every MTA write. Same as Linux.
- Move the location of calling wm_set_filter. Same as some other OSes.
- Flush writing WMREG_CTRL in wm_gmii_mediachange().
- Make new wm_phy_post_reset() and use this function at all location
  after resetting phy.
- Add I219 specific workaround for legacy interrupt. From OpenBSD.
- Move the location of calling wm_lplu_d0_disable().
- Disable D0 LPLU on 8257[12356], 82580, I350 and I21[01], too. Before
  this commit, above devices and non-PCIe devices accessed wrong
  register.
- Fix latency calculation in wm_platform_pm_pch_lpt().
- Set OBFF water mark and enable OBFF on PCH_LPT and newer.
- Fix a bug that wm_gmii_i82544_{read,write}reg() didn't take care of
  page select. PHY access from igphy() automatically did it, but
  accessing from wm(4) for workaround didn't work correctly. This
  change affects 8254[17], 8257[12] ICH8, ICH9 and ICH10.
- Call wm_kmrn_lock_loss_workaround_ich8lan() before any PHY access in
  wm_linkintr_gmii().
- Register access in wm_kmrn_lock_loss_workaround_ich8lan() now works
  correctly. Enable this function.
- IF TX is not required to flush, RX is also not required to flush in
  wm_flush_desc_rings(). Same as other OSes.
- Remove wrong semaphore access in wm_nvm_{read,write}_{ich8,spt} to
  prevent hangup. A semaphore is get/put in wm_nvm_{read,write}.
- Move some initialization stuff in wm_attach() before wm_reset().
  Some flags and callback function is required to set correctly before
  wm_reset() because wm_reset() and some helper functions refer them.
- Add wm_write_smbus_addr() to set SMBus address by software.
- Modify wm_gmii_hv_{read,write}reg_locked() to make them access
  HV_SMB_ADDR correctly.
- Configure the LCD with the extended configuration region in NVM if
  it's required. Tested with Thinkpad X220.
- 8257[12]: Don't directly access SPI but use EERD register.
- 82575-I354: If the size of SPI ROM >= 32K words, use direct SPI
  access instead of EERD register access.
- Add wm_nvm_eec_clock_raise() and wm_nvm_eec_clock_lower() and use
  them for Microwire/SPI bus control. Same as Linux and FreeBSD.
- Reduce timeout value for 80003 in wm_get_swfw_semaphore(). Same as
  Linux and FreeBSD.
- Change API of kmrn_{read,write}reg() and check the return value.
- Check whether it's required to use MDIC workaround for 80003 or not
  in wm_reset(). If the workaround isn't required, don't use the
  workaround code in wm_gmii_i80003_{read,write}reg.
- Add WM_F_WA_I210_CLSEM flag for a workaround. FreeBSD/Linux drivers
  say "In rare circumstances, the SW semaphore may already be held
  unintentionally." on I21[01]. PXE boot is one of the case.
- Qemu's e1000e emulation (82574L)'s SPI has only 64 words. I've never
  seen on real 82574 hardware with such small SPI ROM. Check
  NVM word size before accessing higher address words to prevent
  timeout.
- Check some wm_nvm_read()'s return vale.
- Use device_printf() instead of aprint_error_dev() for PHY read/write
  functions because those are used not only in device attach.
- Print internal driver flags when attaching.
- Add debug printf()s.
- Rename variables.
- Add comment, update comment and remove wrong comment.
