[PATCH] PCI/P2PDMA: Add Alibaba T-HEAD Yitian 710 to whitelist

[Feng Tang]

Alibaba T-HEAD Yitian 710 surports PCI peer-to-peer transactions. Add it
to the P2P whitelist.

2 NVME cards with CMB (Command  Memory Buffer) have run p2pmem-test [1]
fine, under same root complex and different root complexes.
