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.
