Subject: [PATCH] arm64: dts: ti: k3-j721s2-main: fix msmc node

On J721S2 SOC, l3cache-sram size is configured as zero by
system firmware.
Also top 64K of msmc_ram (0x703F_0000 to 0x703F_FFFF) is used by system
firmware tifs-sram.

This patch removes l3cache-sram node and update range for tifs-sram.

Fixes: b8545f9d3a54 ("arm64: dts: ti: Add initial support for J721S2 SoC")
