[Nouveau] [PATCH] renouveau/nv10: remove duplicate vertex buffer registers

NV10TCL defines the vertex buffer registers both as arrays and as
individual named registers.

This causes duplicate register definitions and the individual registers
are not used either by the DDX or by the Mesa driver.

Francisco Jerez said to remove them all.

I am experimenting with rewriting renouveau-gen.c in Python, and
stored registers in a dictionary with the register offset as key.

Having multiple registers at the same offset obviously causes issues
with that, and this is the only instance of that problem, so it seems
better to remove it than adding complexity to tools to handle it.
