Hi all,

Fixed some comments, while haven't made the design decision according
to Laurent's question of heap implementation.

We need Debian & Fedora folks to confirm if any DMA heap or udmabuf
would be available by default to make progress.

BR,
Harvey

  libcamera: Move DmaHeap to HeapAllocator as a base class
  libcamera: Add UdmaHeap if DmaHeap is not valid
  libcamera: Add exportFrameBuffers in HeapAllocator
