[PATCH 6/7] clk: imx6: do pfd workaround unconditionally

The i.MX6D and i.MX6Q SoC variants need a workaround for the PFDs which
may not work properly when they are not gated/ungated once during
startup. We currently have this workaround twice, once in the clock
driver and once in imx6_init_lowlevel(). The latter will be removed, but
before doing that the workaround in the clock driver is done
unconditionally and not only when the IPU driver is enabled.
