clk: of: fix clk_of_table generation 

We used to collect all sections beginning with __clk_of_table_ in a single
section in the linker using KEEP(*(.__clk_of_table_*)). That the sentinel
entry ended up as the last entry was pure luck, but not always the case.

Instead of putting all entries in different sections we now put all entries
in the same section. Only the sentinel entry gets its own section and is
collected by the linker separately.
