[PATCH] PCI: rockchip: Correct the register value for clearing client interrupts

[Brian Norris <briannorris@chromium.org>]

I'm pretty sure the bitwise 'or' was meant for the value parameter, not
the register parameter.

This resolves an interrupt storm, where if we receive any client IRQs
(e.g., correctable errors), we fail to ever clear them properly, so they
reoccur indefinitely.

Fixes: 199410f6270e ("PCI: rockchip: Add Rockchip PCIe controller support")
