Subject: [PATCH] ucm2: Add config for Rockchip/rk3399-gru-sound

This is the internal card for a number of ChromeOS devices based on the
Gru board. Config is taken from ChromeOS sources [1] and modified to
mostly look like Rockchip/max98090. Tested on a Samsung Chromebook Plus
(rk3399-gru-kevin) running Linux 5.7+.
