Maxime Ripard 8f1fc1bf1a dma: contiguous: Reserve default CMA heap
The CMA code, in addition to the reserved-memory regions in the device
tree, will also register a default CMA region if the device tree doesn't
provide any, with its size and position coming from either the kernel
command-line or configuration.

Let's register that one for use to create a heap for it.
