We can move all the IMX clock drivers into drivers/clk at some point
when necessary.  But I do not have a plan to register all the clocks
by merely calling of_clk_init(), because doing that would mean we have
to represent all these clocks in device tree.  For imx6q example, it's
about 200 ~ 300 nodes addition to DTB.  Device tree maintainers are
against to the idea.  They are perfectly fine with having clock driver
in kernel to represent/register these SoC internal clocks to clk
framework.
