mmc: add MODALIAS linkage for MMC/SD devices
Currently we are using an explicit udev rule to trigger loading of the
mmc-block module when an MMC or SD card is detected:
SUBSYSTEM=="mmc", RUN+="/sbin/modprobe -Qba mmc-block"
It makes much more sense for the mmc bus driver and the mmc-block module to
share MODALIAS information so that they are linked automatically.
There is no real information of use in the MMC system at the current time.
All devices inserted require us to load the mmc-block device. Until such
time as useful parameters exist simply reflect the module linkage via
the module alias below:
mmc:block
