net: stmmac: dwmac4: mask interrupts when stopping DMA in suspend
Since commit 1b9707e6f1a9 ("net: stmmac: enable RPS and RBU
interrupts"), suspending causes an interrupt storm from the RPS
interrupt.
Fix this by adding a deinit_chan() op to stmmac_dma_ops, which
masks all default dma channel interrupts. This is called from
stmmac_stop_all_dma(), so interrupts don't trigger while suspending.
Fixes: 1b9707e6f1a9 ("net: stmmac: enable RPS and RBU interrupts")
