platform/x86/amd/pmc: Add spurious_8042 to Xbox Ally

[ Upstream commit c0ddc54016636dd8dedfaf1a3b482a95058e1db2 ]

The Xbox Ally features a Van Gogh SoC that has spurious interrupts
during resume. We get the following logs:

atkbd_receive_byte: 20 callbacks suppressed
atkbd serio0: Spurious ACK on isa0060/serio0. Some program might be trying to access hardware directly.

So, add the spurious_8042 quirk for it. It does not have a keyboard, so
this does not result in any functional loss.
