fastboot: check for alias when looking up partition by name

Browse Source 
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

Fastboot partition aliases can also be defined 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. Current implentation checks
aliases when accessing partitions by name (flash_write and erase functions).
To define a partition alias add an environment variable similar to:
fastboot_partition_alias_<alias partition name>=<actual partition name>
Example: fastboot_partition_alias_boot=LNX
