mmc: meson-mx-sdhc: Set MANUAL_STOP for multi-block SDIO commands

commit f89b548ca66be7500dcd92ee8e61590f7d08ac91 upstream.

The vendor driver implements special handling for multi-block
SD_IO_RW_EXTENDED (and SD_IO_RW_DIRECT) commands which have data
attached to them. It sets the MANUAL_STOP bit in the MESON_SDHC_MISC
register for these commands. In all other cases this bit is cleared.
Here we omit SD_IO_RW_DIRECT since that command never has any data
attached to it.

This fixes SDIO wifi using the brcmfmac driver which reported the
following error without this change on a Netxeon S82 board using a
Meson8 (S802) SoC:
  brcmf_fw_alloc_request: using brcm/brcmfmac43362-sdio for chip
                          BCM43362/1
  brcmf_sdiod_ramrw: membytes transfer failed
  brcmf_sdio_download_code_file: error -110 on writing 219557 membytes
                                 at 0x00000000
  brcmf_sdio_download_firmware: dongle image file download failed

And with this change:
  brcmf_fw_alloc_request: using brcm/brcmfmac43362-sdio for chip
                          BCM43362/1
  brcmf_c_process_clm_blob: no clm_blob available (err=-2), device may
                            have limited channels available
  brcmf_c_preinit_dcmds: Firmware: BCM43362/1 wl0: Apr 22 2013 14:50:00
                         version 5.90.195.89.6 FWID 01-b30a427d
