Subject: [PATCH] arm64: dts: ti: k3-j722s: Fix main domain GPIO count

J722S does not pin out all of the GPIO same as AM62P and have
more number of GPIO on the main_gpio1 instance. Fix the GPIO
count on both instances by overriding the ti,ngpio property.

Fixes: ea55b9335ad8 ("arm64: dts: ti: Introduce J722S family of SoCs")

More details at J722S/AM67 Datasheet (Section 5.3.11, GPIO):
