dmaengine: xilinx_dma: Clear desc_pendingcount in xilinx_dma_reset
[ Upstream commit 8a631a5a ] Whenever we reset the channel, we need to clear desc_pendingcount along with desc_submitcount. Otherwise when a new transaction is submitted, the irq coalesce level could be programmed to an incorrect value in the axidma case. This behavior can be observed when terminating pending transactions with xilinx_dma_terminate_all() and then submitting new transactions without releasing and requesting the channel.
