[PATCH 4/4] arm64: dts: amlogic: t7: fix the pin groups of the vsync PWM

[Lucas Tanure]

The vsync PWM output can appear on either of two pins, but the
description named a single group that does not exist, so anything using
it would refuse to start.

Name the real groups instead, one entry per pin. No board describes this
output yet, so nothing changes today.
