Qiang, Mani

I have a RTS5261 mmc chip on PCIe3 on the Surface Laptop.
Adding the global irq breaks sdcard detection (the chip still comes
up fine) somehow. Removing the irq makes it work again :|

I've confirmed that the irq number is correct
Actually, I verified this patch with several devices (SDX75, AIC100 and
R8169 of TP-LINK) attached to X1E80100 QCP. But I didn't meet this issue.
Each device was detected. Can you please share boot log if it is possible?

Mani, did you ever meet similar issue on other platforms?
