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 v6

Fixed unused variable warning

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
