soc/intel/cmn/block/acpi: enable BERT table without crashlog

Besides crashlog, there's also other errors such as MCA error, which
should be recorded in BERT table. With current code, BERT table is
not generated if crashlog is not enabled. Add if statement for
SOC_INTEL_CRASHLOG so that MCA error can be recorded in BERT table
when crashlog is not supported.
For some server mainboard, crashlog is supported through BMC instead
of host firmware.

Also check if BERT region is generated when crashlog is not enabled.
