[U-Boot] [PATCH 2/2] dfu, nand: add medium specific polltimeout function

Thu Apr 10 07:08:06 CEST 2014
add a possibility to add a medium specific polltimeout
function. So it is possible to define different
poll timeouts.
Used on nand medium, for setting the DFU_MANIFEST_POLL_TIMEOUT
only on nand ubi partitions, which is currently the only
usecase.
