Various problems will happen if clk parent was set up directly.
it should use clk_reparent()

7784f4da1a sh: clkfwk: sh_clk_init_parent() should be called after clk_register()
sh_clk_init_parent() are using clk->mapped_reg
which is mapped in clk_register()

56242a1fc5 sh: clkfwk: setup clock parent from current register value
Some clocks can select its parent clock by CPG register.
But it might have been modified by boot-loader or something.
This patch removed fixed initial parent clock,
and setup it from their current register settings.
It works on div6 reparent clocks for now.

52c10ad22b sh: clkfwk: fixup clk_rate_table_build parameter in div6 clock
div6 clock should not use arch_flags for clk_rate_table_build,
because SH_CLK_DIV6_EXT doesn't care .arch_flags.
clk->freq_table[] will be all CPUFREQ_ENTRY_INVALID without this patch.

f278ea849e sh: clkfwk: Build fix for non-legacy CPG changes.
The disabling of the init op for non-legacy clocks neglected to do the
same in the core clock framework, resulting in a build failure. Fix it
up.

35a96c739f sh: clkfwk: Kill off now unused algo_id in set_rate op.
Now that clk_set_rate_ex() is gone, there is also no way to get at rate
setting algo id, which is now also completely unused. Kill it off before
new clock ops start using it.

de9186c257 sh: clkfwk: Shuffle around to match the intc split up.
This shuffles the clock framework code around to a drivers/sh/clk subdir,
to follow the intc split up. This will make it easier to subsequently
break things out as well as plug in different helpers for non-CPG users.
