arm64: dts: ti: k3-j721s2: Add GPU node

The J721S2 binding is based on the TI downstream binding in commit
54b0f2a00d92 ("arm64: dts: ti: k3-j721s2-main: add gpu node") from [1]
but with updated compatible strings.

The clock[2] and power[3] indices were verified from HTML docs, while
the interrupt index comes from the TRM[4] (appendix
"J721S2_Appendix_20241106_Public.xlsx", "Interrupts (inputs)",
"GPU_BXS464_WRAP0_GPU_SS_0_OS_IRQ_OUT_0").
