[PATCH 6.1.y 1/3] mmc: sdhci-pci-gli: Use PCI AER definitions, not hard-coded values

[Sasha Levin <sashal@kernel.org>]

From: Bjorn Helgaas <bhelgaas@google.com>

[ 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.
