arm64: dts: ti: am62-phyboard-lyra: Add overlay to increase cpu frequency to 1.4 GHz

The am625 is capable of running at 1.4 GHz when VDD_CORE is increased
from 0.75V to 0.85V. Increasing the voltage while the AM625 is
running has not been validated by TI, so we provide an overlay so that
people may choose to run at 1.4 GHz if they need the additional
performance.
