uart: split it and use dataflow
...
This make the code easier to understand and allow the reuse of UARTRX & UARTTX
on designs without CPU (e.g miscope).

mila: add clk_domain support
...
an AsyncFIFO is inserted when clk_domain is not "sys" to enable capture from another clock domain.
sys_clk frequency need to be greater than clk_domain clock.
future possible improvement: automatic insertion of a converter when clk_domain frequency is
greater than sys_clk.

- use sys_clk of 166.66MHz and using it instead of sata clk.
- rename clocking to CRG since it also handles resets.
- create datapath and move code from gtx.

add generic CRCEngine, CRC32, CRCInserter and CRCChecker
...
CRCEngine implements a generic and optimized CRC LFSR. It will enable generation of CRC generators and checkers.
CRC32 is an implementation of IEEE 802.3 CRC using the CRCEngine.
CRC32Inserter and CRC32Checker have been tested on an ethernet MAC.

targets: add simple design (vendor agnostic and usable on all platforms with UART pins).
...
Designing a SoC with Migen is easy, but we have to provide a very simple design that can
be used on all boards with only 1 clock and 2 UARTs pins defined. This will encourage the
newcomer to invest time in Migen/MiSoC and see its real potential.
