712a341c76 imx8mq: Set ARM core clock directly from ARM PLL
For ARM core clock, there are two input branches, and can select via mux:
one from ARM PLL directly, second from CCM A53 clock root.

Currently we are using second branch. But IC confirmed the CCM A53 root
signoff timing is 1Ghz, so we should switch to input from ARM PLL directly.

This patch fixes the CORE SEL slice configuration and switch ARM clock
to ARM PLL.

2dfecdd1ed imx: imx8mq: add init_nand_clk
Add init_nand_clk to enable gpmi nand clock. Since i.MX8MQ not use CCF,
so we still use legacy mode to configure the clock.

8838cdf10d imx8m: restructure clock.h
i.MX8MQ and i.MX8MM use different analog pll design, but they
share same ccm design.
Add clock_imx8mq.h for i.MX8MQ
keep common part in clock.h
