memory: omap-gpmc: Fix a couple off by ones
[ Upstream commit 4c54228ac8fd55044195825873c50a524131fa53 ]
These comparisons should be >= instead of > to prevent reading one
element beyond the end of the gpmc_cs[] array.
Fixes: cdd6928c589a ("ARM: OMAP2+: Add device-tree support for NOR flash")
Fixes: f37e4580c409 ("ARM: OMAP2: Dynamic allocator for GPMC memory space")
