arm64: dts: ti: k3-j721e: Fix the L2 cache sets

[ Upstream commit e9ba3a5bc6fdc2c796c69fdaf5ed6c9957cf9f9d ]

A72's L2 cache[1] on J721e[2] is 1MB. A72's L2 is fixed line length of
64 bytes and 16-way set-associative cache structure.

1MB of L2 / 64 (line length) = 16384 ways
16384 ways / 16 = 1024 sets

Fix the l2 cache-sets.
