Subject: [PATCH v3 2/2] arm64: dts: ti: k3-j784s4-evm: Add support for OSPI and QSPI flashes
J784S4 has S28HS512T OSPI flash connected to OSPI0 and MT25QU512A QSPI
flash connected to OSPI1, enable support for the same. Also describe
the partition information according to the offsets in the bootloader.
