The fixed rate clock driver could be used to represent oscillator
clocks. Platforms that need to determine the rate of the oscillator
clock frequency would require that the fixed rate clock driver
be available for use prior to relocation. So add the
DM_FLAG_PRE_RELOC property to the driver flags.

Can you instead use the u-boot,dm-pre-reloc property in the DT? This
change will affect everyone.
