dfu, nand: add medium specific polltimeout function

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.
