Subject: [PATCH v3 2/2] platform/x86/amd: pmf: Use META + L for screen lock command

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

In practice userspace software doesn't react to KEY_SCREENLOCK by default.
So any time that the PMF policies would suggest to lock the screen (for
example from an HPD sensor event) userspace isn't configured to do it.

However userspace is configured for META + L as this is the default
in the PC ecosystem. Adjust the PMF driver to select the Kconfig option
that makes the input core send META + L.
