ACPICA: acpidump: Convert the default behavior to dump from /sys/firmware/acpi/tables
ACPICA commit 04c3bd7e9d6aeb2b3edebe99c90dc271ae4e6353
In order to work without any additional option to dump tables when /dev/mem
doesn't exist, this patch switches the default behavior of acpidump to dump
from /sys/firmware/acpi/tables. Reported by Al Stone, Fixed by Lv Zheng.
