Looking at a quick output of:
grep -r -A10 early_devices[[] arch/sh/kernel/
it looks like all of the existing early platform devices are serial ports, clocks, and clocksources. The switch to device tree should pick them all up from CLK_OF_DECLARE, TIMER_OF_DECLARE, and EARLYCON_DECLARE. Until that's complete, the existing code works as-is. I don't see what problem you're trying to solve.
FYI I'm (sometimes-somewhat-absent) arch/sh co-maintainer.
