clk: mxs: Include clk.h in C files that use it

Clock provider drivers generally shouldn't include clk.h because
it's the consumer API. The clk.h include is being included in all
mxs files because it's part of mxs/clk.h even though nothing
actually requires it in that file. Move the clk.h include to the
C files that are actually using it and remove the clk.h include
from the header file. The clkdev.h include isn't used either, so
drop it too.

clk: make several parent names const

Since commit 2893c379461a ("clk: make strings in parent name arrays
const") the name of parent clocks can be const. So add more const in
several clock drivers.

clk: add CLK_SET_RATE_NO_REPARENT flag

Add a CLK_SET_RATE_NO_REPARENT clock flag, which will prevent muxes
being reparented during clk_set_rate.

To avoid breaking existing platforms, all callers of clk_register_mux()
are adjusted to pass the new flag. Platform maintainers are encouraged
to remove the flag if they wish to allow mux reparenting on set_rate.
