Commit 3fa5fce "Cleaning up fifos" accidentally changed TARGET from XILINX to GENERIC
This commit fixes this problem and moved TARGET assignment to the top level
Fixes CRITICAL WARNING: [Designutils 20-1280] Could not find module 'fifo_async_104x32'.

Vivado does not pre-process defines in the module declaration.
The result is that each module with this type of declaration is AutoDisabled by Vivado
Moving the top level define to a localparam fixes this problem

Commit 381ba09 adds CFG_ASIC as a primary variable. This commit
allows this to be set in the system_build.tcl script at build time

- adding missing reset on pulse/edge detectors
- disconnecting unused signals in spi clockdivider
- changin output to input on spi_slave_io for read data
- Hiding project name, is a true "global". It defines the flavor of the project and will never be overridden at instantiation...so fine
- Adding CFG_ASIC as a default in parameter statement...because generally you need the ability to override but carrying it all the way through the hierarchy is just annoying...
- The act of putting in a synchronizer should be scalar!
- Putting in vectors should be hard and explicit (thus we make them scalars)
- This is in contrast to most other cells which are vectorized by default
- "which one is not like the others applies to this cell"
- Also cleaning up some chip synthesis warnings/errors
-Need to separate between open FPGA design and closed ASIC design.
-NDAs means it's imposssible for us to disclose even the interfaces of the cells inside without taking the risk of violating the terms of the NDA.
-For this reason, we come up with generic and clean asic library interfaces that need to be implemented in each library/technology
- modified 64b interface
- adding some other address widths/types
- making AW/PW orthogonal for added flexibility, this means wheneve these blocks are used, you have to specify AW/PW
- making 32/104 the default for backwards compatibility
- changing to v2005 interface
- adding license
