[PATCH 3/7] arm64: dts: ti: k3-j721s2: Add Wave5 Video Encoder/Decoder node

[Brandon Brnich]

From: Darren Etheridge <detheridge at ti.com>

Add the Chips and Media wave521cl video decoder/encoder node on J721S2.

This functional block also requires an SRAM buffer as a bandwidth saving
temporary store so we need to add a carve out of 126K for this as
specified in the documentation.

Wave521cl needs to use CMA as there is no IO MMU on J721S2-evm. Each
1080p channel requires roughly 98-100 MB. Allocate 896 MB to meet 8
channel capability for J721S2-evm.
