Subject: [PATCH 4.19 76/91] drivers/usb/typec/tps6598x.c: fix portinfo width

From: Nikolaus Voss <nikolaus.voss@...wensteinmedical.de>

commit 05da75fc651138e51ff74ace97174349910463f5 upstream.

Portinfo bit field is 3 bits wide, not 2 bits. This led to
a wrong driver configuration for some tps6598x configurations.

Fixes: 0a4c005bd171 ("usb: typec: driver for TI TPS6598x USB Power Delivery controllers")
