cpufreq: acpi-cpufreq: Report if CPU doesn't support boost technologies
There is some rare cases where CPB (and possibly IDA) are missing on
processors.
This is the case fixed by commit f7f3dc00f612 ("x86/cpu/AMD: Fix
erratum 1076 (CPB bit)") and following.
In such context, the boost status isn't reported by
/sys/devices/system/cpu/cpufreq/boost.
This commit is about printing a message to report that the CPU
doesn't expose the boost capabilities.
This message could help debugging platforms hit by this phenomena.
