all: fixed reset on .car file insertion

I should have mentioned before the EclaireXl builds are now going in the standard area, though there aren't really significant improvements to that in these builds.
build_A2EBArom is v1
build_A4EBArom is v2 (board marked v3)
build_A4EBAromv3 and build_A2EBAromv3 is the mini. You need to use the appropriate one for your FPGA.
