When experimenting with fastboot from U-Boot on the Raspberry Pi 3 we
found that the writes to the sdcard are much more slow than when
accessing it from the userspace. These two patches speed up the write
and allow us to reliably write the sdcard from U-Boot.

  mmc: sdhci: Wait for SDHCI_INT_DATA_END when transferring.

  mmc: bcm2835_sdhci: Speed up mmc writes.
