  Hi,

Here comes the bcm2835 sdhost driver, with all cleanups squashed in, so
you see just the final result without all the inividual cleanup steps.

Patch #2 is the actual driver, commit message has some more info on the
driver.  Patches 1+3 add the device tree bits.

Patch #4 is the big red switch which activates the driver.

Tested on a rpi2 so far, and in PIO mode only.  Will looking at enabling
DMA next, and fixing whatever comes up in review of course.

please review & test,
  Gerd
