PCI/P2PDMA: Add Zhaoxin host bridges to allowlist
Zhaoxin host bridges support peer-to-peer DMA. Add their device IDs
(0x1003, 0x1005-0x1008) to the allowlist so p2pdma works on these
platforms.
The entries cover the KX-6000, KH-40000, KX-6000G, KX-7000 and KH-50000
families.
Mark the KX-6000/KH-40000/KX-6000G/KX-7000 entries REQ_SAME_HOST_BRIDGE
because P2P requests are only supported between devices below the same host
bridge. KH-50000 doesn't have this restriction.
