As much as we have grown used to seeing this message on
every kernel boot, it does not add any technical value.

Demote the init banner to pr_debug() like other similar
messages in the driver and drop the copyright message
altogether.

Why do we need a print at all during module init?

Typically sdhci drivers end up printing a message at the log level if
they succeed to probe in __sdhci_add_host() - along with the other
error/debug messages during ->probe(). That seems sufficient to me,
but I'm not sure what other people think.

Kind regards
Uffe

I tend to agree.  In include/linux/module.h it says
/* Each module must use one module_init(). */
but I am not sure that is true.  If not, maybe sdhci_drv_init()
and sdhci_drv_exit() could be removed.
