Add support for ARM Common Platform Error Record (CPER).
UEFI 2.6 specification adds support for ARM specific
processor error information to be reported as part of the
CPER records. This provides more detail on for processor error logs.

The memory error record structure includes as its first field a
bitmask of which subsequent fields are valid. The allows new fields
to be added to the structure while keeping compatibility with older
software that parses these records. This mechanism was used between
versions 2.2 and 2.3 to add four new fields, growing the size of the
structure from 73 bytes to 80. But Linux just added all the new
fields so this test:
if (gdata->error_data_length >= sizeof(*mem_err))
cper_print_mem(newpfx, mem_err);
else
goto err_section_too_small;
now make Linux complain about old format records being too short.
Add a definition for the old format of the structure and use that
for the minimum size check. Pass the actual size to cper_print_mem()
so it can sanity check the validation_bits field to ensure that if
a BIOS using the old format sets bits as if it were new, we won't
access fields beyond the end of the structure.

In latest UEFI spec(by now it is 2.4) memory error definition
for CPER (UEFI 2.4 Appendix N Common Platform Error Record)
adds some new fields. These fields help people to locate
memory error to an actual DIMM location.

We have a lot of confusing names of functions and data structures in
amongs the the error reporting code. In particular the "apei" prefix
has been applied to many objects that are not part of APEI. Since we
will be using these routines for extended error log reporting it will
be clearer if we fix up the names first.

The AER error information printing support is implemented in
drivers/pci/pcie/aer/aer_print.c. So some string constants, functions
and macros definitions can be re-used without being exported.
The original PCIe AER error information printing function is not
re-used directly because the overall format is quite different. And
changing the original printing format may make some original users'
scripts broken.

On some machine, PCIe error is reported via APEI (ACPI Platform Error
Interface). The error data is passed from firmware to Linux via CPER
PCIe error section structure.
This patch adds CPER PCIe error section structure and constants
definition.

The abbreviation of severity should be SEV instead of SER, so the CPER
severity constants are renamed accordingly. GHES severity constants
are renamed in the same way too.

CPER stands for Common Platform Error Record, it is the hardware error
record format used to describe platform hardware error by various APEI
tables, such as ERST, BERT and HEST etc.
For more information about CPER, please refer to Appendix N of UEFI
Specification version 2.3.
This patch mainly includes the data structure difinition header file
used by other files.
