If suspend event is received by MDP before panels, MDP needs to ensure
other panels are off before turning MDP clocks off. Remove handlers from
framebuffer driver and handle all suspend logic within MDP driver to
handle this scenario.

Current clock logic only considers panel pixel clock to calculate mdp
clock speed, MDP clock speed should also consider other factors such
as surface scaling. Bus scaling should also consider surface scaling
factor. Update logic to consider these new factors and perform these
performance updates together.

When panel size is increased dma_alloc_coherent is not able to find
a chunk of contiguous memory big enough to hold framebuffer, this causes
framebuffer initialization to fail. Allocate buffer from ion pool which
has reserved contiguous memory at earlier stage.

Debug writeback is used to output MDSS framebuffer contents to memory to

writeback buffer instead of using memory from framebuffer base layer to

gpu: ion: several bugfixes and enhancements of ION
1. Verifying if the size of memory allocation in ion_alloc() is aligned
by PAGE_SIZE at least. If it is not, this change makes the size to be
aligned by PAGE_SIZE.
2. Unmaps all mappings to the kernel and DMA address spaces when
destroying ion_buffer in ion_buffer_destroy(). This prevents leaks in
those virtual address spaces.
3. Makes the return value of ion_alloc() to be explicit Linux error code
when it fails to allocate a buffer.
4. Makes ion_alloc() implementation simpler. Removes 'goto' statement and
relavant call to ion_buffer_put().
5. Checks if the task is valid before calling put_task_struct() due
to failure on creating a ion client in ion_client_create().
6. Returns error when buffer allocation requested by userspace is failed.
