6b87b3f4dc imx8m: update clock root and fix core_sel
Update clock root table to let it be easy to configure clock at
very early stage. Also the core_sel mux parent should be A53 CLK
root and ARM PLL.

126dcc925d ARM: imx: imx8mm: Add missing clock entries for FEC clock
All the FEC ethernet clock entries for iMX8MM are missing, while they
are already present on iMX8MQ. Fill in the nodes on iMX8MM, as the FEC
ethernet gets bogus clock information otherwise which makes ethernet
inoperable.

291e3ab904 imx8mm/mn: Add missing root clock entry for ARM core clock
The current implementation in arch/arm/mach-imx/cpu.c uses non-DM
code to retrieve the core clock frequency. As the root clock is not
listed we currently get:

CPU:   Freescale i.MX8MMQ rev1.0 at 0 MHz

Fix this by adding the missing entry, which results in:

CPU:   Freescale i.MX8MMQ rev1.0 at 1200 MHz

db4510ff8e imx: imx8mp: add basic clock
i.MX8MP has similar architecture as i.MX8MN, but it has different
clk root and index, so add that to make i.MX8MP could use
the non-dm clock driver.

f4c36ab6ee imx8m: add clk support for i.MX8MN
i.MX8MN has similar architecture with i.MX8MM, so it could reuse
the clock code of i.MX8MM, but i.MX8MN has different CCM root
configurations, so need a separate root entry.

5f24d0cb9c imx8m: add clk support for i.MX8MM
Introduce clk implementation for i.MX8MM, including pll configuration,
ccm configuration. Mostly will be done clk dm driver,
but such as DRAM part, we still use non clk dm driver, because we
have limited sram.
