The important part where this connects to the mmc-spi driver is that you need to set spi_board_info->modalias to "mmc-spi", if the device node can be identified as an mmc card.
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).
Then you call that function after registering the master, from mpc52xx_psc_spi_of_probe.
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.
