Console log from boot till root-fs prompt with lots of sdhci_bcm0 error messages.

Hello,

a RPI3 with a CURRENT kernel newer as commit 8a8166e5bcfb50e2b7280581b600d098fa6c9fc7
lost ist ability to find the root filesystem while a lot of

  dhci_bcm0-slot0: Cannot issue a command (power=21 clock=0)
  sdhci_bcm0-slot0: Cannot issue a command (power=21 clock=0)mmc0: CMD7 failed,
  RESULT: 4

messages appear on the console.

I have attached a console log from booting the kernel till the prompt
for a root-fs.

The causing commit was found by bisecting.
As the commit message "mmc: switch mmc_helper to device_ api" and the
changed files suggests, this issue is directly related.
