iio: frequency: adf41513: driver implementation

- ADF41513: 1 GHz to 26.5 GHz frequency range
- ADF41510: 1 GHz to 10 GHz frequency range
- Integer-N and fractional-N operation modes
- Ultra-low phase noise (-235 dBc/Hz integer-N, -231 dBc/Hz fractional-N)
- High maximum PFD frequency (250 MHz integer-N, 125 MHz fractional-N)
- 25-bit fixed modulus or 49-bit variable modulus fractional modes
- Programmable charge pump currents with 16x range
- Digital lock detect functionality
- Phase resync capability for consistent output phase
- Clock framework integration for system clock generation
