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