Here's some updates to etnaviv, which augment the features and GPU specifications which we export to userspace. This will allow us to fix the (currently incorrect) number of varyings that GPUs such as GC880 and GC2000 supposedly have.
While making this change, I'm also increasing the number of feature words we export up to the largest number known from the current Vivante galcore code.
