ACPI: RISC-V: Remove unnecessary CPPC debug message
The presence or absence of the CPPC SBI extension is currently logged
on every boot. This message is not particularly useful and can clutter
the boot log. Remove this debug message to reduce noise during boot.

This change has no functional impact.

ACPI: RISC-V: Add CPPC driver
Add cpufreq driver based on ACPI CPPC for RISC-V. The driver uses either
SBI CPPC interfaces or the CSRs to access the CPPC registers as defined
by the RISC-V FFH spec.
