pmdomain: imx: gpcv2: use proper helper for property detection

[ Upstream commit 6568cb40 ]

Starting with commit c141ecc3 ("of: Warn when of_property_read_bool()
is used on non-boolean properties"), probing the gpcv2 device on i.MX8M
SoCs leads to warnings when LOCKDEP is enabled.

Fix this by checking property presence with of_property_present as
intended.
