fastboot: check for alias when looking up partition by name
Implement an alias name check for devices where GPT limitations prevent
user-friendly partition names such as "boot", "system" and "cache". Or,
where the actual partition name doesn't match a standard partition name
used commonly with fastboot.
To set an alias, add an environment setting as follows:
fastboot_partition_alias_<alias partition name>=<actual partition name>
Example: fastboot_partition_alias_boot=LNX

In Action
=========
Enter into fastboot by executing the fastboot command in u-boot and you
