The only difference in Verilog is that we avoid creating new Interface and doing
`new_interface.connect(interface)`, so this shouldn't make any difference, but
this somehow generates the error in Vivado (tested on v2018.3 and v2019.2).

liblitesdcard/sdcard: adjust card-ready timeout
Testing on nexys4ddr and rocket, approximately 12 iterations of the
timeout loop (using `busy_wait(1)`) are needed to receive a "ready"
response from the SDcard, assuming a "warm" reset where the card has
already been previously initialized.
If the SDcard is ejected and re-inserted, or if the board is "cold-reset"
(e.g., reprogrammed via openocd vs. a simple push of the reset button),
it takes approximately 450 iterations before the SDCard responds with a
"ready" message.
In either case, a timeout of 10 is insufficient. This patch increases
the busy-wait to 10, and the timeout loop counter to 128, which should
cover most cases.
Additionally, make a few minor cosmetic improvements.
