In some subsystems (eg. CAN, SPI), the max link rate supported can be less
than 1 Mbps and if the unit for max_link_rate is Mbps then it can't be
used. Therefore, leave the decision of units to be used, to the producer
and consumer.

UHS-I speed modes are supported in AM65 S.R. 2.0 SoC[1].
Add support by removing the no-1-8-v tag and including the voltage
regulator device tree nodes for power cycling.
