Subject: [PATCH 1/6] wifi: ath10k: sdio: simplify module initialization

This driver's initialization functions do not perform any custom code,
except printing messages.  Printing messages on modules
loading/unloading is discouraged because it pollutes the dmesg
regardless whether user actually has this device.  Core kernel code
already gives tools to investigate whether module was loaded or not.

Drop the printing messages which allows to replace open-coded
module_sdio_driver().

Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@...aro.org>

FYI:
I have ongoing patchset touching few lines above this patch chunk
(sdio_driver) which might go via different tree. If that patchset is
applied via different tree, it might result in a trivial conflict, but
there is no dependency. They can go via separate trees (except that
trivial conflict).
