PCI/AER: Rationalize error status register clearing

The AER interfaces to clear error status registers were a confusing mess:

  - pci_cleanup_aer_uncorrect_error_status() cleared non-fatal errors
    from the Uncorrectable Error Status register.

  - pci_aer_clear_fatal_status() cleared fatal errors from the
    Uncorrectable Error Status register.

  - pci_cleanup_aer_error_status_regs() cleared the Root Error Status
    register (for Root Ports), the Uncorrectable Error Status register,
    and the Correctable Error Status register.

Rename them to make them consistent:

  From                                     To
  ---------------------------------------- -------------------------------
  pci_cleanup_aer_uncorrect_error_status() pci_aer_clear_nonfatal_status()
  pci_aer_clear_fatal_status()             pci_aer_clear_fatal_status()
  pci_cleanup_aer_error_status_regs()      pci_aer_clear_status()

Since pci_cleanup_aer_error_status_regs() (renamed to
pci_aer_clear_status()) is only used within drivers/pci/, move the
declaration from <linux/aer.h> to drivers/pci/pci.h.
