platform/x86/amd/pmc: Disable keyboard wakeup on AMD Framework 13
The Laptop 13 (AMD Ryzen 7040Series) BIOS 03.03 has a workaround included in the EC firmware that will cause the EC to emit a "spurious" keypress during the resume from s0i3 [1]. This series of keypress events can be observed in the kernel log on resume. ``` atkbd serio0: Unknown key pressed (translated set 2, code 0x6b on isa0060/serio0). atkbd serio0: Use 'setkeycodes 6b <keycode>' to make it known. atkbd serio0: Unknown key released (translated set 2, code 0x6b on isa0060/serio0). atkbd serio0: Use 'setkeycodes 6b <keycode>' to make it known. ``` In some user flows this is harmless, but if a user has specifically suspended the laptop and then closed the lid it will cause the laptop to wakeup. The laptop wakes up because the ACPI SCI triggers when the lid is closed and when the kernel sees that IRQ1 is "also" active. The kernel can't distinguish from a real keyboard keypress and wakes the system. Add the model into the list of quirks to disable keyboard wakeup source. This is intentionally only matching the production BIOS version in hopes that a newer EC firmware included in a newer BIOS can avoid this behavior.
