  Revert "PCI: acpiphp: Reassign resources on bridge if necessary" (2023-12-15 14:55:10 -0600)

----------------------------------------------------------------
- Limit Max_Read_Request_Size (MRRS) on some MIPS Loongson systems because
  they don't all support MRRS > 256, and firmware doesn't always initialize
  it correctly, which meant some PCIe devices didn't work (Jiaxun Yang)

- Add and use pci_enable_link_state_locked() to prevent potential deadlocks
  in vmd and qcom drivers (Johan Hovold)

- Revert recent (v6.5) acpiphp resource assignment changes that fixed
  issues with hot-adding devices on a root bus or with large BARs, but
  introduced new issues with GPU initialization and hot-adding SCSI disks
  in QEMU VMs and (Bjorn Helgaas)
