If the 'queue_priority_mapping' is not provided, we need to allocate the
correct amount of memory. Each entry takes 2 s8, so actually less memory
than needed is allocated.
Update the size of each entry when the memory is devm_kcalloc'ed.

Note that the devm_kcalloc() in edma_xbar_event_map() looks also spurious.
However, this looks fine to me because of the 'nelm >>= 1;' before the
'for' loop.
