This patch is to consolidate SDHCI driver for Freescale eSDHC
controller found on both MPCxxx and i.MX platforms.  It merges
sdhci-of-esdhc.c into sdhci-esdhc.c, so that the same pair of
.probe/.remove hook works with eSDHC for two platforms.

As the results, sdhci-of-esdhc.c and sdhci-esdhc.h are removed, and
header esdhc.h containing the definition of esdhc_platform_data is
put into the public folder.

I agree with Anton about not merging the two...

Agree.

The use of cpu_is_mx..() in the driver itself seems a churn to me
even without this consolidation patch.  Is it possible for us to
eliminate them by using pdata, and eventually device tree?  When we
are there, I might want to revisit the consolidation again.
