[PATCH] arm: dts: k3-j721s2*: Enable OSPI1 with 32-bit address mappings for R5 SPL

[Anurag Dutta]

The R5 SPL requires 32-bit address mappings for OSPI1(QSPI) access.
Override the OSPI1 node with appropriate 32-bit register ranges to
enable proper address translation on the 32-bit R5 core, while
preserving 64-bit mappings for A72 cores. While at it, remove the
disabled status override for ospi1 node to support booting from
qspi.
