[PATCH v5] drivers/platform/x86/amd: pmf: Update screen lock actions to KEY_SCREENSAVER

[Mario Limonciello <superm1@kernel.org>]

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

Screen lock actions are ignored by popular desktop environments currently.
This is because `KEY_SCREENLOCK` is not one of the legacy keys that popular
desktop environments listen to by default, `KEY_SCREENSAVER` is.

Adjust the PMF driver to use the correct keycode.

v5:
 * As Dmitry pointed out that GNOME listens to multiple keys even if not advertised
   it meant there was a bug either in GNOME or the PMF driver.  Turns out it's in the PMF driver!
   Switch key combinations instead of using META+L
