ACPICA: acpiexec/acpinames: Support very large number of ACPI tables
ACPICA commit ca3bd4c5cdc39a9009280032adbbc20f34e94c47 Fix a couple of issues with >40 ACPI tables. Return exit error for acpinames to enable use with BIOS builds. The new exported function is used by acpinames. For Linux kernel, this change is a no-op.
