pmdomain: imx-gpcv2: Suppress bind attrs

The gpcv2 drivers on imx8m series are registered as platform
devices and this opens the possibility of reloading the driver
at runtime.

But this doesn't actually work. There are some hardware sequence
dependecy between blk ctrl and gpc, also power domains are used
by other peripherals, so fix this by explicitly suppressing bind
attrs.
