gemini: Fix up sysupgrade platform.sh script

Browse Source 
The Storlink reference designs sometimes fail upgrade because
not the entire partition is used, so the size isn't equal to
the actual flash space available for the partition.

Fix this by calculating the actual partition sizes by measuring
across the partition offsets instead.
