issues with zynqGrabber

[arrenglover]

The following issues are known for the zynqGrabber

• on Gen1 the bias done flag should(?) be set at the end of programming the biases. It doesn't seem to be, but biases are correctly programmed
• gen3 configure needs print statements between functions. It's not simply for the delay as adding delays instead doesn't work. Typically it's a bad memory bug that does/doesn't occur by chance under different conditions of the compiler. Therefore adding the print statements changes the final binary file by chance such that things work
• the RPC modification of biases has been removed and should (?) be put back
• the register definitions file is a bit of a mess and could be moved to have definitions defined be more local to the device that needs it
• clean-up includes to only necessary
