Several SoCs implement platform drivers for clocks rather than
CLK_OF_DECLARE().  Clocks should come earlier because they are
prerequisites for many of other drivers.  It will help to mitigate
EPROBE_DEFER issues.

Also, drop the comment since it does not look valuable.

Changes in v2:
  - Move clk/ above dma/ since DMA drivers generally enable clk
