gowin: Add partnumbers and packages to the chipdb

Browse Source 
Instead of parsing the partnumber with a regular expression,
a simple table is used. This is done because the structure
of the partnumber changes as new features appear (e.g., ES instead of C6/I5)

This commit does not yet disable the very first regular expression check.
