6496498a62 rockchip: clk: rk3288: limit gpll and cpll init to SPL build
The gpll and cpll init values are only used in rk_clk_init in the SPL
and therefore produce compile time warnings in regular uboot builds.
Fix that with an #ifdef.

3a8a42d955 rockchip: clk: Support setting ACLK
Add basic support for setting the ARM clock, since this allows us to run
at maximum speed in U-Boot. Currently only a single speed is supported
(1.8GHz).

5564ed5dd9 rockchip: rk3288: Move rockchip_get_cru() out of the driver
This function is called from outside the driver. It should be placed into
common SoC code. Move it.

Also rename the driver symbol to be more consistent with the other rockchip
clock drivers.

abd0128eb1 rockchip: remove log2 reimplementation from clock drivers
The already available ilog2 function does exactly the same in the common
case than the log2 function the current clock-driver reimplement.
So, simply move to that one.

fd4b2dc059 clock: rk3399: add support for dwmmc 400K
MMC core will use 400KHz for card initialize first and then switch to
higher frequency like 50MHz, we need to support both 400KHz and about
50MHz for dwmmc controller.

aff8795c01 move: rockchip: move clock drivers into a subdirectory
With the number of Rockchip clock drivers increasing, don't clutter up
the core drivers/clk directory with them and instead move them out of
the way into a separate subdirectory.
