[ Upstream commit 951b7ccc54591ba48755b5e0c7fc8b9623a64640 ]
015c9cbcf0ad ("mmc: sdhci-pci-gli: GL9750: Mask the replay timer timeout of AER") added PCI_GLI_9750_CORRERR_MASK, the offset of the AER Capability in config space, and PCI_GLI_9750_CORRERR_MASK_REPLAY_TIMER_TIMEOUT, the Replay Timer Timeout bit in the AER Correctable Error Status register.
Use pci_find_ext_capability() to locate the AER Capability and use the existing PCI_ERR_COR_REP_TIMER definition to mask the bit.
This removes a little bit of unnecessarily device-specific code and makes AER-related things more greppable.
