ACPICA: Namespace: Add function to directly return normalized full path

Browse source 
ACPICA commit 6e0229bb156d71675f2e07dc7960adb7ec0a60ea

This patch adds functions to return normalized full path instead of
"external path". The external path contains trailing "_" for each
name segment while the normalized full path doesn't contain the
trailing "_".

Currently this function is used by the method tracing users to specify a
none trailing "_" attached name path. Lv Zheng.

Note that we need to validate and switch all Linux kernel acpi_get_name()
users to use the new name type before removing the old name type from
ACPICA.
