We need to enable this controller so that we can switch the SD card's
pinmux over to it by default, which will improve storage performance.

Read access (dd with 64k blocks on rpi2):
  CONFIG_MMC_SDHCI_IPROC: 11-12 MB/s
  CONFIG_MMC_BCM2835:     19-20 MB/s

Differences on write access are pretty much in the noise.

Normally this change should go via the arm64 tree. However as the new
CONFIG_MMC_BCM2835 is added in this series, perhaps it makes sense to
that I pick it up. In such case I need an ack from some of the arm64
soc
folkz, like Catalin/Will.

Kind regards
