Remove the unused wrapper and rework the rest in order to prepare
for removing the non clk_hw based ones.

Remove all the helpers that are not referenced anywhere
anymore. Most of them are not clk_hw based. The rest are
passing the device as an argument and were intented for
BLK_CTL driver usage, but that is not the case anymore since
the BLK_CTL is (or will be) implemented outside of CCF.

Implement the clk based helpers as macros rather than as inline
functions. Once all the provider drivers have switch to clk_hw,
all the clk based macros will go away.

Instead of having multiple inline functions that were calling
clk_hw_register_gate, implement a generic low-level __imx_clk_hw_gate
and implement the rest as macros that pass on as arguments whatever
is needed in each case.

Instead of having multiple inline functions that were calling
clk_hw_register_mux, implement a generic low-level __imx_clk_hw_mux
and implement the rest as macros that pass on as arguments whatever
is needed in each case.

Rather than having multiple different macros for each different type
of imx8m_clk_hw_composite, implement them in such a way so we can
take advantage the most of the already defined simpler types. Basically,
we end up having one low-level __imx8m_clk_hw_composite function, a
wrapper to simplify the parents related arguments called
_imx8m_clk_hw_composite and then all the types can use those for each
specific case.
