Subject: [PATCH 5.10 136/238] pinctrl: mediatek: Drop bogus slew rate register range for MT8192

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

[ Upstream commit e15ab05a6b3ed42f2f43f8bd1a1abdbde64afecd ]

The MT8192 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.
