xhci: dbc: Remove dbc_dma_alloc_coherent() wrapper
dbc_dma_alloc_coherent() takes struct xhci_hcd pointer as an parameter, but
does nothing more than calls dma_alloc_coherent().
Remove it and call dma_alloc_coherent() directly instead.
No functional changes
This change helps decoupling xhci and DbC
