arch: arm: mach-omap2: mmc: Move omap_mmc_notify_cover_event() prototype 

When building the kernel with W=1 the build system complains of:

 drivers/mmc/host/omap.c:854:6: warning: no previous prototype for ‘omap_mmc_notify_cover_event’ [-Wmissing-prototypes]
 854 | void omap_mmc_notify_cover_event(struct device *dev, int num, int is_closed)
 | ^~~~~~~~~~~~~~~~~~~~~~~~~~~

If we move the prototype into a shared headerfile the build system
will be satisfied.  Rather than create a whole new headerfile just
for this purpose, it makes sense to use the already existing
mmc-omap.h.
