Is mrvl8787 a removable card ?

I'm asking because we already skip mmc_sdio_init_card() for
powered-resumed nonremovable cards (check out commit 3cfc33a "mmc:
sdio: don't reinitialize nonremovable powered-resumed cards").

I'm not familiar with marvell's cards, but I do remember a thread
mentioning they have dedicated reset GPIOs, and that may suggest they
are nonremovables. If that's the case, simply setting
MMC_CAP_NONREMOVABLE on the relevant slot should do the trick for you.
