_X, Make it uniformly: _D.

The source ID register offset for Skylake server is 0xf0, while for
Icelake server is 0xf8. Pass the correct offset to get the source ID.

The i10nm_edac only checks the ECC enabling status for the first
channel of the memory controller. If there aren't memory DIMMs
populated on the first channel, but at least one DIMM populated
on the second channel, it will wrongly report that the ECC for
the memory controller is disabled that fails to load the i10nm_edac
driver. Fix it by checking ECC enabling status per channel.
[Tony: Also report which channel has ECC disabled]

Two new CPU models share the same memory controller
architecture with Jacobsville/Tremont, so can use the
same i10nm EDAC driver.
Add ICX and ICX-D CPU model numbers for EDAC support.

The following Kconfig constellations fail randconfig builds:
CONFIG_ACPI_NFIT=y
CONFIG_EDAC_DEBUG=y
CONFIG_EDAC_SKX=m
CONFIG_EDAC_I10NM=y
or
CONFIG_ACPI_NFIT=y
CONFIG_EDAC_DEBUG=y
CONFIG_EDAC_SKX=y

with:
...
CC [M] drivers/edac/skx_common.o
...
.../skx_common.o:.../skx_common.c:672: undefined reference to `__this_module'
That is because if one of the two drivers - skx_edac or i10nm_edac - is
built-in and the other one is a module, the shared file skx_common.c
gets linked into a module object by kbuild. Therefore, when linking that
same file into vmlinux, the '__this_module' symbol used in debugfs isn't
defined, leading to the above error.
Fix it by moving all debugfs code from skx_common.c to both skx_base.c
and i10nm_base.c respectively. Thus, skx_common.c doesn't refer to the
'__this_module' symbol anymore.
Clarify skx_common.c's purpose at the top of the file for future
reference, while at it.

This driver supports the Intel 10nm series server integrated memory
controller. It gets the memory capacity and topology information by
reading the registers in PCI configuration space and memory-mapped I/O.
It decodes the memory error address to the platform specific address
by using the ACPI Address Translation (ADXL) Device Specific Method
(DSM).
