Subject: [PATCH 2/9] staging: media: atomisp: declare 'struct device' before using it

In some configurations, including this header leads to a warning:

drivers/staging/media/atomisp//pci/sh_css_firmware.h:41:38: error: declaration of 'struct device' will not be visible outside of this function [-Werror,-Wvisibility]

Make sure the struct tag is known before declaring a function
that uses it as an argument.

Fixes: 9d4fa1a16b28 ("media: atomisp: cleanup directory hierarchy")
