APLIC source IDs are in the range 1..riscv,num-sources. Device Tree interrupt specifiers contain a source ID directly, while ACPI specifiers contain a GSI that must first be translated by subtracting gsi_base. The shared helper currently checks only whether the raw specifier is zero. An ACPI GSI equal to gsi_base therefore becomes source ID zero, a GSI below gsi_base underflows, and either firmware interface can provide a source ID above the configured count. These values later reach d->hwirq - 1 register and saved-state indexing. Pass the configured source count to the shared helper and validate the translated ID before returning it. This covers both direct and MSI modes.
