Subject: [PATCH 1/6] dt-bindings: clk: meson: add sm1 periph clock controller bindings

Update the documentation to support clock driver for the Amlogic SM1 SoC.

SM1 clock tree is very close, the main differences are :
- each CPU core can achieve a different frequency, albeit a common PLL
- a similar tree as the clock tree has been added for the DynamIQ Shared Unit
- has a new GP1 PLL used for the DynamIQ Shared Unit
- SM1 has additional clocks like for CSI, NanoQ an other components
