dma: amba-pl08x: use vchan_dma_desc_free_list
vchan_dma_desc_free_list() iterates through each virt_dma_desc in the
specified list_head and calls vchan->desc_free().
We can use it instead of repeated execution of pl08x_desc_free() for each
virt_dma_desc in the list_head. Because vchan->desc_free callback is set
as pl08x_desc_free() for amba-pl08x driver.
