b3f635ad66 mmc, sdhci, bcm-kona, LLVMLinux: Remove use of __initconst
The __initconst is in the wrong place, and when moved to the correct place
it uncovers an error where the variable is used by non-init data structures.

Instead merely make them const and put the const in the right spot.

2137f5d3b8 mmc: remove .owner field for drivers using module_platform_driver
This patch removes the superflous .owner field for drivers which
use the module_platform_driver API, as this is overriden in
platform_driver_register anyway.

96d7b78cfc mmc: sdhci: convert sdhci_set_uhs_signaling() into a library function
Add sdhci_set_uhs_signaling() and always call the set_uhs_signaling
method.  This avoids quirks being added into sdhci_set_uhs_signaling().

03231f9b78 mmc: sdhci: convert reset into a library function
Rather than having platform_reset_enter/platform_reset_exit methods,
turn the core of the reset handling into a library function which
platforms can call at the appropriate moment in their (new) reset
method.

ff1acfd0de mmc: sdhci-bcm-kona: Use sdhci_pltfm_unregister instead of open coded
This avoid duplicated implementation and also fixes missing iounmap() and
release_mem_region() calls in sdhci_bcm_kona_remove().  sdhci_pltfm_init()
calls request_mem_region() and ioremap(), thus we need to call the
corresponding iounmap() and release_mem_region() calls in
sdhci_bcm_kona_remove().

aea237bfa0 ARM: DT: binding fixup to align with vendor-prefixes.txt (drivers)
[ this is a follow-up to this discussion:
http://archive.arm.linux.org.uk/lurker/message/20130730.230827.a1ceb12a.en.html ]
This patchset renames all uses of "bcm," name bindings to
"brcm," as they were done prior to knowing that brcm had
already been standardized as Broadcom vendor prefix
(in Documentation/devicetree/bindings/vendor-prefixes.txt).
This will not cause any churn on devices because none of
these bindings have made it into production yet.
