platform/x86: intel-vbtn: Allow switch events on Acer Switch Alpha 12

stable inclusion
from stable-5.10.4
commit 054c923fd376b5d23db4621a7aea35d2f0e990a6
bugzilla: 46903

--------------------------------

commit fe600099 upstream.

This 2-in-1 model (Product name: Switch SA5-271) features a SW_TABLET_MODE
that works as it would be expected, both when detaching the keyboard and
when folding it behind the tablet body.

It used to work until the introduction of the allow list at
commit 8169bd3e ("platform/x86: intel-vbtn: Switch to an allow-list
for SW_TABLET_MODE reporting"). Add this model to it, so that the Virtual
Buttons device announces the EV_SW features again.

Fixes: 8169bd3e ("platform/x86: intel-vbtn: Switch to an allow-list for SW_TABLET_MODE reporting")
