linux-imx_3.14.28: fix initial MMC device detection
On Variscite Varsom we have three devices connected to MMC
* MMC1: eMMC
* MMC2: SDCard
* MMC3: Wifi
Without this patch only the first device was detected properly.
I found two workarounds which can be removed by this patch:
1. Variscite: booting from SDCard made possible by renumbering MMC devices [1].
2. BoundaryDevices: Add workqueues for each mmc_host [2]. This had been tested
here too but causes crashing sdcard for huge storage traffic.
