[PATCH] ACPI: RISC-V: Remove unnecessary CPPC debug message

[PATCH] ACPI: RISC-V: Remove unnecessary CPPC debug message

[Sunil V L]

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.

Thanks, I'm pleased to no longer see the "NOT dectected!!" when testing
defconfig on systems which don't have the CPPC extension.
