SVN rev 210313 on 2010-07-20 19:38:38Z by jkim

- According to ACPICA User Guide and Programmer Reference, the read data
must be zero extended to fill the 32-bit or 64-bit return value even if
the bit width of the port or location is less than 32 or 64.
- Use pmap_mapdev()/pmap_unmapdev() to map device memory instead of using
AcpiOsMapMemory()/AcpiOsUnmapMemory() (-> pmap_mapbios()/pmap_unmapbios())
for AcpiOsReadMemory() and AcpiOsWriteMemory(). Although they do not sound
too obvious, these functions are exclusively used to access memory mapped
IO in ACPICA.
- Remove 64-bit access from AcpiOsReadMemory() and AcpiOsWriteMemory().
These functions do not support 64-bit access. Likewise, return error when
64-bit access is requested for PCI configuration space.
- Simplify AcpiOsReadPort() and AcpiOsWritePort() with iodev_read_*() and
iodev_write_*(). This removes unnecessary uses of temporary macros as well.
There is no functional change after this (verified with md5(1) on amd64).
