mmc: litex_mmc: set PROBE_PREFER_ASYNCHRONOUS

commit f334ad47683606b682b4166b800d8b372d315436 upstream.

mmc host drivers should have enabled the asynchronous probe option, but
it seems like we didn't set it for litex_mmc when introducing litex mmc
support, so let's set it now.

Tested with linux-on-litex-vexriscv on sipeed tang nano 20K fpga.
