stable inclusion from stable-5.10.64 commit f72fce5507097309de4dd6df3faac12c87e61fd9 bugzilla: 182256 https://gitee.com/openeuler/kernel/issues/I4EG0U
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
commit b8da302e2955fe4d41eb9d48199242674d77dbe0 upstream.
pci_device_add() calls HEADER fixups after pci_configure_device(), which configures Max Payload Size.
Convert MPS-related fixups to EARLY fixups so pci_configure_mps() takes them into account.
