disk: part: Add API to get partitions with specific driver
Adds part_driver_get_type() API which can be used to force a specific driver to be used when getting partition information instead of relying on auto detection. Signed-off-by: Joshua Watt <JPEWhacker@gmail.com> Reviewed-by: Simon Glass <sjg@chromium.org>
