mmc: meson-mx-sdio: Set MMC_CAP_WAIT_WHILE_BUSY

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
