Subject: [PATCH v3 01/10] arm64: dts: mediatek: mt6779: Remove syscon compatible from pin controller

From: Yassine Oudjana <y.oudjana@...tonmail.com>

Remove syscon compatible string from pin controller to follow
DT bindings and pass checks. Adding the syscon compatible to
the DT bindings documentation instead causes a different check
error due to the syscon document specifying a maximum of 1 item
in the reg property, while this has 9. This pin controller has
never been, and will never be, used as a syscon, hence it is
safe to drop this compatible.
