Thomas Andreatta e12a50e362 dmaengine: sh: setup_xref error handling 
[ Upstream commit d9a3e99294 ]

This patch modifies the type of setup_xref from void to int and handles
errors since the function can fail.

`setup_xref` now returns the (eventual) error from
`dmae_set_dmars`|`dmae_set_chcr`, while `shdma_tx_submit` handles the
result, removing the chunks from the queue and marking PM as idle in
case of an error.
