Subject: [PATCH v2 10/10] ARM: berlin: rework chip and system controller nodes for BG2Q
The chip and system controller nodes are now handled by the Berlin
controller mfd driver. Its sub-devices are then registered by the mfd
driver and let the drivers be probed properly, using their own
sub-nodes.
Rework the device tree to take this changes into account.
