arm64: zynqmp: Describe 25MHz fixed clock for PL GEMs
Describe 25Mhz fixed oscilator which is providing clock for PL based
ethernet IPs. Physicially it is one chip but it is described as 2 fixed
clock to be aligned with other SOM versions which were using integrated
clock generators where clocks could be adjusted via i2c (si5332 chips).
