arm64: dts: ti: k3-am62p: Add gpio-reserved-ranges for main_gpio1
Commit 29075cc09f43 ("arm64: dts: ti: Introduce AM62P5 family of
SoCs") introduced the main_gpio1 node and included the ti,ngpio
property, but did not include the gpio-reserved-ranges property. As a
result, the user could try to access gpios that do not exist. Fix this
by introducing the gpio-reserved-ranges property.
The non-existent gpios are found in the am62p datasheet [1] in Table
5-24.
Depends on patch: dt-bindings: gpio: gpio-davinci: Add the
gpio-reserved-ranges property [2]
