PCI/AER: Refactor cper_print_aer() for use by CXL driver module
The CXL driver plans to use cper_print_aer() for logging restricted CXL
host (RCH) AER errors. cper_print_aer() is not currently exported and
therefore not usable by the CXL drivers built as loadable modules. Export
the cper_print_aer() function. Use the EXPORT_SYMBOL_NS_GPL() variant
to restrict the export to CXL drivers.
The CONFIG_ACPI_APEI_PCIEAER kernel config is currently used to enable
cper_print_aer(). cper_print_aer() logs the AER registers and is
useful in PCIE AER logging outside of APEI. Remove the
CONFIG_ACPI_APEI_PCIEAER dependency to enable cper_print_aer().
The cper_print_aer() function name implies CPER specific use but is useful
in non-CPER cases as well. Rename cper_print_aer() to pci_print_aer().
Also, update cxl_core to import CXL namespace imports.
