Siddharth Vadapalli 7cbf7f4bf7 dmaengine: ti: k3-udma-glue: Add function to request TX chan for thread ID

The existing function k3_udma_glue_request_tx_chn() supports requesting
a TX DMA channel by its name. Add a new function to request TX DMA channel
for a given thread ID, named k3_udma_glue_request_tx_chn_for_thread_id().
Also, export it for use by drivers which are probed by alternate methods
(non device-tree) but still wish to make use of the existing DMA APIs. Such
drivers could be informed about the thread ID corresponding to the TX DMA
channel by RPMsg for example.

Since the new function k3_udma_glue_request_tx_chn_for_thread_id() reuses
most of the code in k3_udma_glue_request_tx_chn(), create a new function
for the common code, named k3_udma_glue_request_tx_chn_common().
