Jisheng Zhang d1a13c5ed3 mmc: sdhci-iproc: use sdhci_pltfm_unregister directly
The sdhci_iproc_remove() is jsut a wrapper to sdhci_pltfm_unregister.
So use the sdhci_pltfm_unregister() for the .remove hook directly.

Stefan Wahren 77cb7d3a4d mmc: sdhci-iproc: add bcm2835 support
Scott Branden from Broadcom said that the BCM2835 eMMC IP core is
very similar to IPROC and share most of the quirks. So use this driver
instead of separate one.

The sdhci-iproc contains a better workaround for the clock domain
crossing problem which doesn't need any delays. This results in a
better write performance.

Btw we get the rid of the SDHCI_CAPABILITIES hack in the sdhci_readl
function.

Stefan Wahren b17b4ab8ce mmc: sdhci-iproc: define MMC caps in platform data
This patch moves the definition of the MMC capabilities
from the probe function into iproc platform data. After
that we are able to add support for another platform more
easily.

Stefan Wahren 9f24b0f254 mmc: sdhci-iproc: Actually enable the clock
The RPi firmware-based clocks driver can actually disable
unused clocks, so when switching to use it we ended up losing
our MMC clock once all devices were probed.

This patch adopts the changes from 1e5a0a9a58 ("mmc: sdhci-bcm2835:
Actually enable the clock") to sdhci-iproc.

Dmitry Torokhov b1ddaa3d06 mmc: sdhci-iproc: fix oops in sdhci_iproc_writew
The driver co-allocates sdhci_iproc_host with sdhci_pltfm_host and so to
access it we need to use sdhci_pltfm_priv() and not pltfm_host->priv.
