arm64: dts: ti: k3-j721e-beagleboneai64: Fix reversed C6x carveout locations
[ Upstream commit 1a314099b7559690fe23cdf3300dfff6e830ecb1 ]
The DMA carveout for the C6x core 0 is at 0xa6000000 and core 1 is at
0xa7000000. These are reversed in DT. While both C6x can access either
region, so this is not normally a problem, but if we start restricting
the memory each core can access (such as with firewalls) the cores
accessing the regions for the wrong core will not work. Fix this here.
