Subject: [PATCH 2/3] platform/x86/amd: pmf: Add 'quiet' to hidden choices

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

When amd-pmf and asus-wmi are both bound no low power option shows
up in sysfs.  Add a hidden choice for amd-pmf to support 'quiet' mode
to let both bind.

Fixes: 688834743d67 ("ACPI: platform_profile: Allow multiple handlers")
