Subject: [PATCH AUTOSEL 6.0 22/44] platform/x86: thinkpad_acpi: Enable s2idle quirk for 21A1 machine type

From: Lennard Gäher <gaeher@...-sws.org>

[ Upstream commit 53e16a6e3e69425081f8352e13e9fd23bf1abfca ]

Previously, the s2idle quirk was only active for the 21A0 machine type
of the P14s Gen2a product. This also enables it for the second 21A1 type,
thus reducing wake-up times from s2idle.
