clk: imx: composite-8m: add imx8m_clk_hw_composite_core
There are several clock slices, current composite code
only support bus/ip clock slices, it could not support core
slice.
So introduce a new API imx8m_clk_hw_composite_core to support
core slice. To core slice, post divider with 3 bits width and
no pre divider. Other fields are same as bus/ip slices.
Add a flag IMX_COMPOSITE_CORE for the usecase.
