Subject: [RESEND PATCH V2 2/2] arm64: dts: ti: k3-am69-sk: Add support for OSPI flash

From: Dasnavis Sabiya <[email protected]>

AM69 SK has S28HS512T OSPI flash connected to MCU OSPI0.
Enable support for the same. Also describe the partition
information according to the offsets in the bootloader.
