soc_core/cpu: add io_regions and deprecate shadow_base (with API retro-compat)
...
The shadow_base parameter has always been difficult to apprehend, replace it with
io_regions (uncached regions) defined user or the CPU.
The equivalent of a shadow_base parameter of 0x80000000 in the old API is:
io_regions = {0x80000000: 0x80000000} # origin, length
It's still possible to use shadow_base with retro-compat, but user is encouraged
to update and features will be removed in the future.

Update README (related to issue #273 )
...
Following my problems with the quick start guide (issue #273 ), I suggest a few modifications to have a "real" quick start guide.

builder: use the SoC's existing shadow base with get_csr_header()
...
Both the SoC and get_csr_header() have independently set defaults
for the value of 'shadow_base'. If the SoC's value was modified,
ensure that get_csr_header() uses the modified value instead of
its own default.

trellis, versa_ecp5: optional '-nowidelut' flag for yosys synth_ecp5
...
Passing '-nowidelut' to yosys' synth_ecp5 command improves area utilization
to the point where a (linux variant) rocket-chip based design will fit on a
versa_ecp5 board. Usually '-nowidelut' incurs a timing penalty, but that is
then mitigated by using DSP inference (enabled by default from yosys commit
8474c5b3).
Off by default, this flag can be enabled by adding '--yosys-nowidelut=True'
to the litex/boards/targets/versa_ecp5.py command line.
