This clock has nothing to do in the PX30 DTSI as it is supposed to be
an input of the SoC. Moving it to the EVB DTS (only board file using
this DTSI) makes more sense. Also, when this clock is not a fixed
clock and comes from eg. a PMIC the situation can be described cleanly
in the device tree (avoids having to delete the fixed-clock node
first).

This clock is not mandatory to boot so it should not break existing
users.
