ARM: tegra: set CONFIG_SYS_MMC_MAX_DEVICE
If CONFIG_API is ever to be enabled on Tegra, this define must be set,
since api/api_storage.c uses it.
A couple of annoyting things about CONFIG_SYS_MMC_MAX_DEVICE
1) It isn't documented in README. The same is true for a lot of similar
defines used by api_storage.c.
2) It doesn't represent MAX_DEVICE but rather NUM_DEVICES, since the
valid values are 0..n-1 not 0..n.
However, I this patch does not address those shortcomings.
