mmc: core: constify the struct device_type usage
Since commit aed65af1cc
("drivers: make device_type const"), the driver
core can properly handle constant struct device_type. Move the sdio_type,
sd_type and mmc_type variables to be constant structures as well, placing
it into read-only memory which can not be modified at runtime.
