d6fb02f054 clk: imx: imx8mq: fix a53 cpu clock
The A53 CCM clk root only accepts input up to 1GHz, CCM A53 root
signoff timing is 1Ghz, however the A53 core which sources from CCM
root could run above 1GHz which violates the CCM.

There is a CORE_SEL slice before A53 core, we need to configure the
CORE_SEL slice source from ARM PLL, not A53 CCM clk root.

The A53 CCM clk root should only be used when need to change ARM PLL
frequency.

Add arm_a53_core clk that could source from arm_a53_div and arm_pll_out.
Configure a53 ccm root sources from 800MHz sys pll
Configure a53 core sources from arm_pll_out
Mark arm_a53_core as critical clock

7a8d3b90bd clk: imx: imx8mq: use imx8m_clk_hw_composite_core
Use imx8m_clk_hw_composite_core to simplify code.

Add new definitions, and X_SRC/CG/DIV will be alias to the new
definitions for backwards compatibility

b04383b6a5 clk: imx8mq: Define gates for pll1/2 fixed dividers
On imx8mq there are 9 fixed-factor dividers for SYS_PLL1 and SYS_PLL2
each with their own gate but these gates are not currently defined in
the clock tree.

Add them between sys1/2_pll_out and the fixed dividers.

010d5166bb dt-bindings: clock: imx8mq: Fix numbering overlaps and gaps
IMX8MQ_CLK_USB_PHY_REF changes from 163 to 153, this way removing the gap.
All the following clock ids are now decreased by 10 to keep the numbering
right. Doing this, the IMX8MQ_CLK_CSI2_CORE is not overlapped with
IMX8MQ_CLK_GPT1 anymore. IMX8MQ_CLK_GPT1_ROOT changes from 193 to 183 and
all the following ids are updated accordingly.
