Subject: [PATCH 3/9] ARM: omap2/n8x0: work around modular omap mmc

From: Russell King <linux@....linux.org.uk>

When the omap driver is built as a module for n8x0,
n8x0_mmc_set_power_menelaus cannot call into the driver:

arch/arm/mach-omap2/board-n8x0.c:374: undefined reference
to `omap_mmc_notify_cover_event'

As a workaround, do not provide that device in this case. This needs
to be fixed properly, e.g. by converting n8x0 to be probed through the
device tree and moving that code into the driver.
