fix(dma): allow pipelined transfers to prevent assertion failures

Browse Source 
Remove strict assertion on data_transfer_type and allow PIPELINED
transfers (treating them as NON_PIPELINED). Some games like Marvel
Cosmic Invasion use pipelined transfers, causing crashes.

Fixes assertion at maxwell_dma.cpp:76
