Check how much smaller can the weight+bias buffers be with different
amount of bits to encode runs of zeroes and choose the smallest one.
This reduces the bandwidth considerably, which is at present the
bottleneck with useful models.
On a Libre Computer Alta AML-A311D-CC, I see these improvements:
MobileNetV1: 15.650ms -> 9.991ms
SSDLite MobileDet: 56.149ms -> 32.692ms

We support the following two core types: GPU and NPU.
Both are using the 3d pipe to submit work so the only way to
differentiate is the nn core count.

We want to fully initialise etna_device_info. We only query the kernel
for these values if the drm driver is recent enough.

This etna_feature enum will be used as abstraction layer. We will add
support for a hardware database - borrowed from the binary blob.
