- 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.
- Clean up some white spaces.
