Subject: [PATCH] dt-bindings: power: gpcv2: add power-domains property

From: Peng Fan <peng.fan@....com>

Some pgc power-domain requires a parent power domain, so
add an optional power-domains property, otherwise there will be
dt check warning:
gpc@...a0000: pgc:power-domain@1: 'power-domains' does not match
any of the regexes: 'pinctrl-[0-9]+'

Fixes: 30af8513bdb5 ("dt-bindings: power: add defines for i.MX8MM power domains")
Signed-off-by: Peng Fan <peng.fan@....com>
