ARM: OMAP2+: Fix build warning when mmc_omap is not built

[ Upstream commit 040ab72ee10ea88e1883ad143b3e2b77596abc31 ]

GCC reports the following warning with W=1:

arch/arm/mach-omap2/board-n8x0.c:325:19: warning:
variable 'index' set but not used [-Wunused-but-set-variable]
325 |  int bit, *openp, index;
    |                   ^~~~~

Fix this by moving CONFIG_MMC_OMAP to cover the rest codes
in the n8x0_mmc_callback().
