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.

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.
