[PATCH 02/11] ACPI: acpica: Constify pathname argument for acpi_get_handle()

[Sakari Ailus <sakari.ailus@linux.intel.com>]

acpi_get_handle() uses the pathname argument to find a handle related to
that pathname but it does not need to modify it. Make it const, in order
to be able to pass const pathname to it.
