dmaengine: pxa_dma: use platform_get_irq_optional
[ Upstream commit b3d726cb8497c6b12106fd617d46eef11763ea86 ]
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: 7723f4c5ecdb ("driver core: platform: Add an error message to platform_get_irq*()")
