[PATCH] add mmc_host slot_name support

[Guillem Jover]

Some OMAP boards support multiple MMC slots, and on current Linux a
sysfs file might be exposed with this information.

Add a new slot_name key to mmc_host to identify the slot position, the
value can be something like 'external'/'internal', or any other unique
identifier that distinguishes its location from the other possible
mmc_host present in the Computer.
