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.

V2: - Drop 'Binding for'
- Drop reg: description
- Drop ref25 from example
V3: - Replace i2c@0 with plain i2c
- Drop reg property from the i2c node
- Add RB from Krzysztof
