mmc: sdhci-pci-gli: GL9763e: Mask the replay timer timeout of AER
Due to a flaw in the hardware design, the GL9763e replay timer frequently
times out when ASPM is enabled. As a result, the warning messages will
often appear in the system log when the system accesses the GL9763e
PCI config. Therefore, the replay timer timeout must be masked.
