dma: fsl_raid: use devm_platform_ioremap_resource

Browse source

Replace the open-coded platform_get_resource() plus devm_ioremap()
sequence with devm_platform_ioremap_resource(), which fetches the
resource, requests the region and maps it in one call. Switch the error
check to IS_ERR()/PTR_ERR() and drop the now-unused struct resource
pointer.

The raideng node has a single reg region (0x320000, 0x10000); the
job-queue/ring children are separate OF devices probed independently, so
the region reservation added by devm_ioremap_resource() is exclusive and
does not introduce overlap failures.
