Delete vp9_dc_only_idct_add_neon.c

The function was merged with vp9_short_idct4x4_1_add (later
vp9_idct4x4_1_add) in d2de1ca3

 and should have been deleted then.

Check the flags, no MFQE for highbit now. Will add highbit support
latter.

Change 72141 introduced a new use of vp9_avg_4x4.
This call needs to switch to using vp9_highbd_avg_4x4
when performing high bitdepth encodes.

If vp9_pick_inter_mode works properly, it should at least check
one coding mode and hence get best_tx_size assigned a valid value.
There is no need to initialize best_tx_size with a legitimate
value before starting the mode search.

Make the variable reduction_fac log2 based and explicitly use
right shift when computing intra_cost_penalty.

Use left shift to replace one multiplication. The computation
outcome remains identical.

Fails to compile. Bad calls to vp9_alloc_frame_buffer
and vp9_realloc_frame_buffer in postproc.c

This reverts commit 399823b6.
