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.

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.
