        sys/dev/pci/if_wm.c: revision 1.565-1.566

- Fix a bug that wm_pll_workaround_i210() is not called on some cases.
   As I wrote in if_wm.c rev 1.329's commit message, There are three cases:
     a) Chip is I211
     b) Chip is I210 and it uses INVM (not FLASH)
     c) Chip is I210 (it uses FLASH) and NVM image version < 3.25
   Before this commit, the workaround function was not called on a) and b).

- Rename function.

Do wm_reset_mdicnfg_82580() on 82580 only.
