MIPS: OCTEON: cvmx-l2c: add the CN66XX L2 geometry

cvmx_l2c_get_set_bits() and cvmx_l2c_get_num_assoc() know the CN63XX as
the only OCTEON II part, so on a CN6635 both fell through to their
"Unsupported OCTEON Model" defaults: 2048 sets, and 8 ways which the
CN3XXX/CN5XXX fuse path - a read of L2D_FUS3, which is not a register
on OCTEON II - then shifted down to 2.

The CN66XX L2 has the CN63XX geometry, 16 ways and 1024 sets, and
reports its fused-off ways in MIO_FUS_DAT3[l2c_crip] like the rest of
OCTEON II, so name it in those three branches. With this the board
reports assoc 16, sets 1024, and cvmx_l2c_lock_line() computes the tag
alias from the right associativity.

The CN68XX and CN61XX are deliberately left alone: their L2 geometry
differs from the CN63XX, and the CN68XX also uses bit <2> of
MIO_FUS_DAT3[l2c_crip], which the decoding here does not handle. I have
no such board to test on.
