[PATCH v2 1/4] clk: actions: Terminate clk_div_table with sentinel element

In order that the end of a clk_div_table can be detected, it must be
terminated with a sentinel element (.div = 0).

Fixes: d85d20053e195 ("clk: actions: Add S900 SoC clock support")

I'm not so sure about usb3_mac_div_table. Maybe the { 0, 8 } element was
meant to be { 0, 0 }? I'd appreciate if someone with access to the
datasheet or hardware could verify what's correct.

v2:
- Add Fixes tags
