This series includes some fixes to INTx masking/unmasking for UniPhier PCIe
host controller driver.

- Remove unnecessary bit clears to INTX mask field
- Remove unnecessary irq_ack() function because write access to status field
  doesn't work
- Add lock into callback functions to avoid race condition

  PCI: uniphier: Fix INTx mask/unmask bit operation and remove ack
    function
