Subject: [PATCH 6.8 400/715] pinctrl: mediatek: Drop bogus slew rate register range for MT8186

From: Chen-Yu Tsai <wenst@...omium.org>

[ Upstream commit 3a29c87548809405bcbc66acc69cbe6f15184d94 ]

The MT8186 does not support configuring pin slew rate. This is evident
from both the datasheet, and the fact that the driver points the slew
rate register range at the GPIO direction register range.

Drop the bogus setting.
