Florent Kermarrec 91981b960c 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)

Gabriel Somlo e9054ef65a 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).

bunnie 5a402264d0 Fix off-by-one error on almost full condition for prefetch
This causes a DRC error on the Xilinx tools when the prefetch
lines setting is 1. Don't know why this wasn't caught earlier,
but it just popped up in CI.

Reclock spi sdcard access after initialisation
Depends upon https://github.com/enjoy-digital/litex/pull/435

After initialising the card, reclock the card, aiming for ~16MHz (divider is rounded up, as slower speed is safer), but a maximum of half of the processor speed.

Tested with the card being clocked to 12.5MHz on de10nano
