ENGR00318063-3: ARM: imx6sx: fix ocram_sels mux setting
The current imx6sx clock driver combines two mux clocks ocram_alt_sel
and ocram_sel into one, while ocram_alt_sel is a glitchy mux and
ocram_sel is a glitchless one. Fix it to match the clock tree in
Reference Manual.
One thing clk API clients need to take care is that clk_set_parent()
can be called on glitchy ocram_alt_sel only when ocram_sel selects the
other path, i.e. periph. Otherwise, a glitch could be generated on
ocram_alt_sel and get propagated into the divider ocram_podf. In that
case, ocram_podf gets locked up and ocram clock has no output.
