Rafael J. Wysocki 2e433a94da ACPI: OSL: Fix and clean up acpi_os_read/write_port() 
First, remove type casts that make acpi_os_read_port() only work on
little endian and are generally not needed.

Second, avoid clearing the memory pointed to by the value return
pointer in acpi_os_read_port() if it is the dummy on the stack (in
which case clearing it is not necessary).

Finally, prevent both acpi_os_read_port() and acpi_os_write_port()
from crashing the kernel when they receive an unsupported width
value and make them print a debug message and return an error instead.
