sdhci_add_host and sdhci_platfm_init already report failure,
so don't emit error messages when a failure occurs. This prevents
occurences of "deferred" messages when required power supplies
are not ready for operation yet.

"ret" is a signed int, so use "%d" in format strings instead of "%u".
This prevents cryptic codes in error messages like this:
sdhci-arasan e0101000.sdhci: platform register failed (4294966779)

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.

Add sdhci_set_uhs_signaling() and always call the set_uhs_signaling
method. This avoids quirks being added into sdhci_set_uhs_signaling().

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.
