Furong Xu e9837c83be net: stmmac: xgmac: fix handling of DPP safety error for DMA channels
[ Upstream commit 46eba193d04f8bd717e525eb4110f3c46c12aec3 ]

Commit 56e58d6c8a ("net: stmmac: Implement Safety Features in
XGMAC core") checks and reports safety errors, but leaves the
Data Path Parity Errors for each channel in DMA unhandled at all, lead to
a storm of interrupt.
Fix it by checking and clearing the DMA_DPP_Interrupt_Status register.
