Looks clean Stefan. I'll try and revisit the caps setting in the future
and may be able to provide additional settings in a later patch.

This patch series based on the suggestion of Scott Branden to implement
bcm2835 support into sdhci-iproc [1].
These changes provide the following advantages:
* no need to maintain a separate driver for bcm2835
* improve support and test coverage of bcm2835 mmc support
* get the rid of SDHCI_CAPABILITIES hack in bcm2835_sdhci_readl
* increase write performance by avoiding delays in write ops
Patch 1 prepare sdhci-iproc for another platform. Patch 2 and 3
are the actually changes for bcm2835 support.
These series has been tested on Raspberry Pi B with dd (direct I/O):
sdhci-bcm2835
378 kB/s WRITE
10,6 MB/s READ
sdhci-iproc (after applying patch series)
881 kB/s WRITE
10,8 MB/s READ
Changes since RFC:
* drop patch which tries to add quirks for bcm2835 in DT and define all
quirks in driver instead to keep old DTs working with sdhci-iproc
(suggestion by Stephen Warren)
* define MMC caps in shdci-iproc platform data to make adding new
platforms more easily (suggestion by Stephen Warren)
