etnaviv: Report correct number of vertex buffers

The GCnano has only 4 vertex buffers instead of 16. This information
can be extracted from the GPU status registers and is already stored
in screen->specs.stream_count. Use PIPE_CAP_MAX_VERTEX_BUFFERS to
report this information and permit u_vbuf to reorganize the shaders
to fit.

This fixes the following dEQP on GCnano:

   n = (2k + 1) * 2^s

for k, s integers. Rather than explicitly store k and s separately and
then compute this formula on demand, it's much cleaner to store the
padded number itself, which is what you manipulate most of the time.
When you do need k,s it is easy to factor by noticing the bitwise
representation:

   s = ctz(n)
   k = n >> (s + 1)

panfrost: Factor out panfrost_compute_magic_divisor

The algorithm doesn't need to be tangled up in details about the

We need to reshuffle to sync up the shadow coordinate temporary with the

Although the swizzle is unaligned, its format is otherwise standard.
