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).

Host address parameter types should match CPU word width, so
use `unsigned long` to be correct on both 32 and 64 bit CPUs.

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
