acpi: rework BERT ACPI table generation logic

Check if the ACPI_BERT Kconfig option is selected and only then try to
generate the BERT table. Also remove the acpi_is_boot_error_src_present
weak function from the ACPI global compilation unit and use the return
value of acpi_soc_get_bert_region to determine if there is a valid BERT
region with logged errors.
