This is a DM clock driver for the imx8mq based on the linux kernel
driver and the u-boot imx8mm clock driver.
It also removes some code duplication in the imx8m[nmp] clock drivers.
Changes since v5
Added UART clocks
Added video clocks
Added DRAM clocks
Changes since v4
Rebased onto [1] so patch 4 of 4 was dropped.
Added CLK_COMPOSITE_CCF
Fixed const* clock definitions
Changes since v3:
Fixed driver spelling
Moved rate macros out of the header into the dot c
Changes since v2:
Added kernel commit IDs
Re-factored rate table code to remove duplication
Remove duplicate code by creating a common clk-imx8m
Changes since v1:
More verbose clock driver description
Added forgotten dt-bindings
Synced PLL frequencies with mainline kernel

This is a DM clock driver based off the imx8mm u-boot driver and the linux
kernel driver.
All of the PLLs and clocks are initialized so the subsystems below are
functional and tested.
1) USB host and peripheral
2) ECSPI
3) UART
4) I2C all busses
5) USDHC for eMMC support
6) USB storage
7) GPIO
8) DRAM
