mmc: tmio: move {tmio_}mmc_of_parse() to tmio_mmc_host_alloc()
mmc_of_parse() parses various DT properties and sets capability flags accordingly. However, drivers have no chance to run platform init code depending on such flags because mmc_of_parse() is called from tmio_mmc_host_probe(). Move mmc_of_parse() to tmio_mmc_host_alloc() so that drivers can handle capabilities before mmc_add_host(). Move tmio_mmc_of_parse() likewise.
