Commit cc6111375cec ("ARM: drop efm32 platform") removed the platform,
so no need to still carry the bindings.

-* Clock bindings for Energy Micro efm32 Giant Gecko's Clock Management Unit
-
-Required properties:
-- compatible: Should be "efm32gg,cmu"
-- reg: Base address and length of the register set
-- interrupts: Interrupt used by the CMU
-- #clock-cells: Should be <1>
-
-The clock consumer should specify the desired clock by having the clock ID in
-its "clocks" phandle cell. The header efm32-clk.h contains a list of available
-IDs.

-Required properties :

- - reg : Offset and length of the register set for the device
