Reverted the file FELIX_gbt_wrapper_V7.vhd to before GBT2CR_RST merge to...

Frans Schreuder requested to merge RevertGBT2CR_RST_Virtex7 into master

Hello @kai, triggered by the test in FLX-956, I discovered that any VC709 bitfile from master after the merge of the branch GBT2CR_RST is not working anymore (no data is coming back over a loopback GBT link). while BNL712 bitfiles are fine.

I think we should revert the FELIX_gbt_wrapper_V7.vhd to before GBT2CR_RST, and re-evaluate the changes for VC709.

This are the bitfiles I tested
