dma: mmp_pdma: add IRQF_SHARED when request irq
For some SOCes use mmp_pdma, they have several dma controllers sharing same irq. So add IRQF_SHARED to flag when request irq. It can make multiple controllers share the same irq. Signed-off-by: Chao Xie <chao.xie@marvell.com> Signed-off-by: Vinod Koul <vinod.koul@intel.com>
