dmaengine: ti: omap-dma: don't allow a null od->plat pointer to be dereferenced
Currently when the call to dev_get_platdata returns null the driver issues
a warning and then later dereferences the null pointer. Avoid this issue
by returning -ENODEV error rather when the platform data is null and
change the warning to an appropriate error message.
Addresses-Coverity: ("Dereference after null check")
Fixes: 211010aeb097 ("dmaengine: ti: omap-dma: Pass sdma auxdata to driver and use it")
