Subject: [RFC PATCH 01/16] pinctrl: ralink: reintroduce ralink,rt2880-pinmux compatible string

From: Arınç ÜNAL <arinc.unal@...nc9.com>

There have been stable releases with the ralink,rt2880-pinmux compatible
string included. Having it removed breaks the ABI. Reintroduce it.

Fixes: e5981cd46183 ("pinctrl: ralink: add new compatible strings for each pinctrl subdriver")
