clk: mediatek: mt7623: set unmapped IDs to -1
Add range initializers to the id_offs_map arrays in the mt7623 clk
driver to set unmapped IDs to -1. This prevents accidental usage of
unmapped IDs that would otherwise map to 0.
mtk_common_clk_of_xlate() checks these values for < 0 and returns
-ENOENT in that case.
A range initializer covering the entire array is used since it is less
error-prone than manually looking up the value of each macro in the
existing initializers and checking for gaps. It is placed first so that
the specific initializers override it.
