mmc: Rename timeout parameters for clarification
It's quite hard to figure out time units for various function that have
timeout parameters. This leads to possible errors when one forgets to
convert ms to us, for example. Let's rename those parameters
correspondingly to 'timeout_us' and 'timeout_ms' to prevent such issues
further.
While at it, add time units info as comments to struct mmc fields.
This commit doesn't change the behavior, only renames parameters names.
Buildman should report no changes at all.
