dmaengine: pxa_dma: use platform_get_irq_optional

The first IRQ is required, but IRQs 1 through (nb_phy_chans - 1) are optional, because on some platforms (e.g. PXA168) there is a single IRQ shared between all channels. This change inhibits a flood of "IRQ index # not found" messages at startup. Tested on a PXA168-based device. Fixes: 7723f4c ("driver core: platform: Add an error message to platform_get_irq*()") Signed-off-by: Doug Brown <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Vinod Koul <[email protected]>
