xhci: dbc: Remove dbc_dma_free_coherent() wrapper

Browse Source 
dbc_dma_free_coherent() takes struct xhci_hcd pointer as a parameter, but
does nothing more than calls dma_free_coherent().
Remove it and call dma_free_coherent() directly instead.

No functional changes
This change helps decoupling xhci and DbC
