Align package name with dependency reference name

Created by: meggiman

Bender has the issue, that most of the time it ignores the name stated in the bender.yml and uses the name used in dependent packages (e.g. riscv core package). All other repos refer to this package as "fpnew" although it is actually called "FPnew". This can cause issues since bender does not realize that there are clashes between identical packages (according to their package name) if the parent packages refer to them under different names. This can cause a whole nightmare of synthesis issues if incompatible versions are involuntarily combined that way.
