Doing that now, using the code you provided as a base. The SPI child
device gets registered, but it appears something is still missing as no
messages I could attribute to mmc-spi appear. My suspicion would be that
it doesn't like the monolithic kernel for some reason (the mmc-spi
driver registers itself as a driver called "mmc_spi", not sure if the
modalias handling will catch that; still investigating there).

I've changed mpc52xx_psc_spi_do_probe to have an additional argument for
the OF device node of the SPI master; ARCH=ppc can call this with NULL
as long as it still exists.
