Pull up following revision(s) (requested by msaitoh in ticket #1229):
sys/arch/x86/pci/ichlpcib.c: revision 1.40, 1.45
sys/dev/pci/pcivar.h: revision 1.101
sys/dev/pci/pci_map.c: revision 1.32
sys/dev/ic/i82801lpcreg.h: revision 1.12
Use '\n' at the end of all aprint_error_dev() format strings.

Fix a bug that ichlpcib(4) maps I/O area incorrectly and then fails to attach
gpio. It might also fixes ACPI related problem described in PR#48960:
- The LPCIB_PCI_PMBASE and LPCIB_PCI_GPIO register are alike PCI BAR but not
completely compatible with it. It's ok because the registers' addresses are
out of BAR0-BAR5(0x10-0x24) and are located in the device-dependent header.
The PMBASE and GPIO registers define the base address and the type but not
describe the size. The size is fixed to 128bytes. So use
pci_mapreg_submap().
- Make pci_mapreg_submap() extern again.
- Fix the calculation of the map size in pci_mapreg_submap().
