Add documentation for RZ/G3S CPG. RZ/G3S CPG module is almost identical
with the one available in RZ/G2{L, UL} the exception being some core
clocks as follows:
- SD clock is composed by a mux and a divider and the divider
  has some limitation (div = 1 cannot be set if mux rate is 800MHz).
- there are 3 SD clocks
- OCTA and TSU clocks are specific to RZ/G3S
- PLL1/4/6 are specific to RZ/G3S with its own computation formula
Even with this RZ/G3S could use the same bindings as RZ/G2L.
