[src/trunk]: src/sys/dev/pci - Fix RAL table's size of PCH2 and PCH_LPT.
details: https://anonhg.NetBSD.org/src/rev/73d09a302d43
branches: trunk
changeset: 812638:73d09a302d43
user: msaitoh <msaitoh%NetBSD.org@localhost>

description:
- Fix RAL table's size of PCH2 and PCH_LPT.
- PCH_LPT (and newer device) is required to check FWSM_WLOCK_MAC bit to
determine the range of the RAL.
- Fix typo in comment and modify comment by tnn@.
- Rename wm_check_reset_block() to wm_phy_resetisblocked() and make it returns
bool. No functional change.
