1. Allocator api is determined by buffer type.
2. Allocator ctx is determined by both buffer type and buffer flags.
3. All allocator dma_heap / drm / ion / ext_dma should support different
buffer flags.
4. The buffer flag supports cacheable / 32-bit / contig options.
5. Add flags update flow on allocator create process.
6. Add mpp_dmabuf_has_partial_ops to disable dmabuf partial ops when the
kernel driver has bug.

sync_begin - cache invalidate, should be called before cpu read
sync_end - cache flush, should be called after cpu write
MppBuffer sync flow:
1. hw access
2. sync_begin
3. cpu access (read / write)
4. sync_end
5. hw access
NOTE: readonly option is faster for read only buffer.

1. Move callback module to osal for later mpp_device callback.
2. Make callback command a pre-defined value to avoid include issue.
3. Separate callback cmd and param to separate header.

Batch mode will send multiple task to kernel at one time. And its
non-block poll is triggered by timer and looper.
This mode will reduce the ioctl overhead on ultra multi-instance case.
Main features and some notes:
1. Each client type has independence batch server.
2. Each mpp_device can attach or not attach to server independently.
3. When a device is attached to server all its tasks will be sent to
kernel through the server session not original client session.
4. The tasks are sent non-block and wait in block or non-block.
5. The batch mode can only be switch on/off when hardware is not
working.

This buffer type is used for the buffer coming from the
application, the application should make sure those
buffers are the dma buffer.

As we found that simple ion / drm device detectioin can not cover all the
case. For example on some 3368 platform kernel provide both ion and drm
device. We have better to use allocator chosen in dts.
But later kernel patch from Randy will bring unified dma-fd translation in
kernel then this detection will be removed.

This reverts commit 8d42511773.
It will cause a problem in the platform skipping those library.
since those libraries are not necessary for any platform,
I think don't link with them would be better.
