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 mpp_log.h to inc for external user.
2. Add mpp_debug.h for mpp internal logging.
3. Fix some warning.
4. Add log level setup function.
5. Check env log_level value in mpp_get_log_level call.
NOTE:
1. mpp internal module should use mpp_debug.h and mpp external user
should use mpp_log.h
2. Use mpp_get_log_level to update mpp_log_level when the env changed.

When decoding in internal buffer mode and source is field mode the
decoder need 3 buffer to continue decoding. But mpp_buffer_group_unused
function only return 1 by default.
This patch return correct value considering the buffer limit count and
buffer group mode.

Each of the different alloctor has different alloctor modes,
such as allocating physical continuous memory, secure memory,
etc.

Sometimes the offset or the offset plus the size is beyond the
buffer area. It would be better to raise an error and stopping
the future step rather than the kernel halt it.

The external buffer would request the index of a buffer to
manage it in an array.

1. Separate mpp_buffer_import_with_tag into two macro for different usage.
2. Add more comment.
3. Change helper macro and function parameter order for better understanding.
