[PATCH -next] mmc: sdhci-omap: Remove forward declaration of sdhci_omap_context_save()

[Geert Uytterhoeven]

If CONFIG_PM_SLEEP=n:

    drivers/mmc/host/sdhci-omap.c:1213:13: error: ‘sdhci_omap_context_save’ declared ‘static’ but never defined [-Werror=unused-function]
     1213 | static void sdhci_omap_context_save(struct sdhci_omap_host *omap_host);
	  |             ^~~~~~~~~~~~~~~~~~~~~~~

The referenced commit added an unrelated forward declaration of
sdhci_omap_context_save(), which is unneeded in general, and unused when
CONFIG_PM_SLEEP=n.
