PCI/ERR: Rename pci_aer_clear_device_status() to pcie_clear_device_status()
pci_aer_clear_device_status() clears the error bits in the PCIe Device
Status Register (PCI_EXP_DEVSTA). Every PCIe device has this register,
regardless of whether it supports AER.
Rename pci_aer_clear_device_status() to pcie_clear_device_status() to make
clear that it is PCIe-specific but not AER-specific. Move it to
drivers/pci/pci.c, again since it's not AER-specific. No functional change
intended.
