ARM: imx6q: clk: Add support for mipi_core_cfg clock as a shared clock gate
The CG8 field of the CCM CCGR3 register is named as 'mipi_core_cfg' clock,
according to the i.MX6q/sdl reference manuals. This clock is actually the
gate for several clocks, including the hsi_tx_sel clock's output and the
video_27m clock's output. The MIPI DSI host controller embedded in the
i.MX6q/sdl SoCs uses the video_27m clock to generate PLL reference clock and
MIPI core configuration clock. In order to gate/ungate the two MIPI DSI
host controller relevant clocks, this patch adds the mipi_core_cfg clock as
a shared clock gate.
