dt-bindings: clk: si521xx: Add Skyworks Si521xx I2C PCIe clock generators 



Add binding for Skyworks Si521xx PCIe clock generators. This binding
is designed to support Si52144/Si52146/Si52147 series I2C PCIe clock
generators, tested model is Si52144. It should be possible to add
Si5213x series as well.
