ACPI/PPTT: Add acpi_pptt_warn_missing() to consolidate logs
For a system using ACPI-based FW without a PPTT, we may get many warnings about the lack of a PPTT, as shown: root@(none)$ dmesg | grep -i pptt [ 0.010125] ACPI PPTT: No PPTT table found, cpu topology may be inaccurate [ 7.138339] ACPI PPTT: No PPTT table found, cache topology may be inaccurate [ 7.145368] ACPI PPTT: No PPTT table found, cache topology may be inaccurate These logs are generated with pr_warn_once(), so the intention was for a single log, but the logs overlap, so consolidate them.
