commit e53b868b3cf5beeaa2f851ec6740112bf4d6a8cb upstream.
The Meson SDIO controller uses the DAT0 lane for hardware busy detection. Set MMC_CAP_WAIT_WHILE_BUSY accordingly. This fixes the following error observed with Linux 5.7 (pre-rc-1): mmc1: Card stuck being busy! __mmc_poll_for_busy blk_update_request: I/O error, dev mmcblk1, sector 17111080 op 0x3:(DISCARD) flags 0x0 phys_seg 1 prio class 0
