EDAC, skx: Fix randconfig builds
The driver depends on the ADXL component glue and selects it. However,
ADXL itself implicitly depends on ACPI and in nonsensical randconfig
builds like this:
# CONFIG_ACPI is not set
CONFIG_ACPI_ADXL=y
where ACPI is not enabled, the build fails with:
drivers/edac/skx_edac.o: In function `skx_mce_check_error':
skx_edac.c:(.text+0xab): undefined reference to `adxl_decode'
drivers/edac/skx_edac.o: In function `skx_init':
skx_edac.c:(.init.text+0x8bf): undefined reference to `adxl_get_component_names'
make: *** [vmlinux] Error 1
Add stubs for that case so that the build succeeds. CONFIG_ACPI=n
doesn't make any sense for real configurations but this fix will at
least silence randconfig builds.
