Run `litex_setup.py` outside the git clone directory.
...
Otherwise it tries to overwrite the litex directory by cloning LiteX
into it.

litex_setup: Use subprocess so failures are noticed.
...
os.system doesn't report if any of the commands fail. This means that if
something goes wrong it happily reports success making it hard to debug
issues.

soc/cores/uart: use reset_less on accumulator, reg, bitcount to reduce.
...
This reduces logic a bit. It does not make large difference on usual design with
only 1 UART, but is interesting on designs with hundreds of UARTs used to "document"
FPGA boards :) (similar to https://github.com/enjoy-digital/camlink_4k/blob/master/ios_stream.py )

software/libbase/spisdcard: add delay to goidle loop
...
In `spi_sdcard_goidle()`, insert a `busy_wait()` into the CMD55+ACMD41
loop to avoid exhausting the retry counter before the card has a chance
to be ready (required on the trellisboard, also tested OK on nexys4ddr).
