[PATCH next 1/3] rockchip: px30: bind sub-nodes for GRF (syscon)

[Quentin Schulz]

From: Quentin Schulz <quentin.sch...@cherry.de>

There are some sub-nodes under the grf DT nodes, so add bind callback
function in syscon_px30 driver to scan them recursively.

Fixes: e9ccb2f526ed ("rockchip: add px30 architecture core")
Signed-off-by: Quentin Schulz <quentin.sch...@cherry.de>
