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.

Changes in v3:
* rename/invert CLK_SET_RATE_REMUX to CLK_SET_RATE_NO_REPARENT and move
to this new patch.
* patch 3: add CLK_SET_RATE_NO_REPARENT flag to all callers of
clk_register_mux. If you don't mind your clocks being reparented in
response to set_rate please let me know and I'll drop the relevant
portion of the patch.
