lima: set uniforms_address lower bits properly

Looks like blob uses following values for uniforms buffer:

0 for 8 bytes 1 for 16 bytes 2 for 24 bytes 2 for 32 bytes 3 for 40 bytes 3 for 48 bytes 3 for 56 bytes 3 for 64 bytes 4 for 72 bytes

It all looks like log2(size / 8) rounded up, so let's do the same.
