[PATCH v2 03/10] dmaengine: imx-sdma: drop legacy device_node np check

[Marco Felsch]

The legacy 'if (np)' was required in past where we had pdata and dt.
Nowadays the driver binds only to dt platforms. So using a new kernel
but still use pdata is not possible, therefore we can drop the legacy
'if' code path.
