Subject: [PATCH v3] mmc: sdhci: Stop advertising the driver in dmesg

From: Linus Walleij <linus.walleij@...aro.org>

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

Drop all messages from sdhci_drv_init(), and drop the
module_init() and module_exit() calls as well since they
now become empty.

The modules becomes a pure library module, meaning it will
get pulled in by modprobe() when the symbols inside it
are needed, or compiled in if any users are compiled in.
Kconfig already makes sure this module is compiled in
the users are compiled in.
