android: ion: fix missing buffer initialization

Every buffer allocated to userspace should be initialized to a
specific pattern to remove data written by previous users of the
memory in the buffer. The initialization should include elimination
of dirty cache lines allocated for a uncached buffer to prevent write
back from dirty cache lines after uncached data write to the buffer.
This write-back corrupts the buffer with the stale data in the cache.

Cache flush on allocation uses __flush_dcache_area() that is not a
kernel API function allowed for the drivers. But we have no chice than
that because dma-mapping API needs a device descriptor configured for
DMA. Instead modifying pseudo device descriptor, ion_device, we have
decided to use ARM64 specific function __funsh_dcache_area() for
convenient maintenance.

android: ion: do not defer free for carveout heap

Carved out heaps allocate buffers from a memory pool of with a limited
size. If it frees buffers in deferred manner, the heap may not be
available in a rare condition by unexpected external fragmentations.
Let's think about the following scenario in a 10MB carveout pool:
  1. allocated 4MB @ +0MB
  2. allocated 2MB @ +4MB
  3. freed 1 but defferred

  5. allocated 3MB @ +6MB
  6. returned buffer 1 and 2 to the heap.
  7. allocated 4MB @ +0MB
  8. allocation of 3MB failed due to the fragmentation.

Any defferred behavior to the very limited resources is harmful.
