clk: mediatek: add support for remapping clock ID

Upstream kernel linux might have a different clock ID order in their
<soc>-clk.h header. This is the case of some clock ID for mt7623 that
upstream use the shared header clk-mt7601.h

This header doesn't have a well distincted order and have factor or mux
in the middle of the CLK ID list. This is problematic with the mtk clock
driver that expect everything well organized in block and apply offset
to reference the clk in the different array.

To solve this problem, implement in the mtk_clk_tree an additional
option .id_offs_map, an array where each CLK ID can be remapped to what
the driver expect permitting to reorganize the clock following the
expected logic of fixed, factor, mux and gates.

Each clock function is updated to tranparently handle this by first
converting the clk ID to the remapped one.
