MXSCM-240-2 arm: dts: imx: make mmdc clk accessible from the busfreq driver
The mmdc clk rate needs to be explicitly updated when moving to
high audio rate by the busfreq module for the i.mx6q lpddr2 systems.
In order to make the mmdc_ch0_axi clk visible by this driver, it
needs to be included on the clocks/clock-names list.
For the imx6dqscm-1gb-evb systems the clocks list for the busfreq
module is originally inherited from imx6q.dtsi. To include the mmdc
clk, the full clocks list plus the mmdc clk needs to be overwriten
on the individual dts files.
