ENGR00154666-3: Align u-boot mmc command with community

This patch will enhance mmc command.
1. Add erase command.
2. Abandon dev_no in mmc command. User need to switch slot with "mmc
dev" command.
3. Add mmc part switch command. Enhance partition switch support.
4. Add mmc bootpart. Boot partition support is more flexible.
