The default size of 16 MiB reserved for CMA is not enough for the
majority of use-cases, so set it to something more sensible.

Note that users can still override this via the cma kernel command-line
argument, which takes precendence over the default specified in the
kernel configuration file.

I've squashed this into Tegra's for-3.15/defconfig branch.

BTW, Tegra patches should probably be CC'd to the ARM kernel list as
well, just so people are aware.
