[RFC] clk: imx6: Mark imx_clk_mux as glitchy by default

With some exceptions clk muxes on imx6 are "glitchy": If the output is not gated before reparenting then high-frequency pulses can occur and cause unpredictable behavior. Only a very small subset of muxes are listed as "glitchless" in the reference manual. Adapt to this by adding the CLK_SET_PAREN
