[RFC PATCH] mmc: dw_mmc: remove redundant num_slots check

num_slots comes from pdata if existing, otherwise from
dw_mci_parse_dt which make it at least one slot. If
num_slots is less than 1 for the existing pdata case,
current code return -ENODEV. But dw_mci_probe seems to
treat this a optional case as it will call SDMMC_GET_SLOT_NUM
if no slot assigned.
