[PATCH v4 REPOST 5/5] imx6q: Remove unconditional dependency on l2x0 L2 cache support

[dave.martin@linaro.org (Dave Martin)]

The i.MX6 Quad SoC will work without the l2x0 L2 cache controller
support built into the kernel, so this patch removes the dependency
on CACHE_L2X0 and selects MIGHT_HAVE_CACHE_L2X0 instead.

This makes the l2x0 support optional, so that it can be turned off
when desired for debugging purposes etc.

Thanks to Shawn Guo for this suggestion. [1]
