Subject: [PATCH 3/8] ACPI: CPPC: Adjust debug messages in amd_set_max_freq_ratio() to warn

From: Mario Limonciello <mario.limonciello@....com>

If the boost ratio isn't calculated properly for the system for any
reason this can cause other problems that are non-obvious.

Raise all messages to warn instead.
