ACPI: Return -ENODEV from acpi_parse_spcr() when SPCR support is disabled
commit b9f58d3572a8e1ef707b941eae58ec4014b9269d upstream.
If CONFIG_ACPI_SPCR_TABLE is disabled, acpi_parse_spcr()
currently returns 0, which may incorrectly suggest that
SPCR parsing was successful. This patch changes the behavior
to return -ENODEV to clearly indicate that SPCR support
is not available.
This prepares the codebase for future changes that depend
on acpi_parse_spcr() failure detection, such as suppressing
misleading console messages.
