cpus: Allocate maximum number of ASes supported by the arch (2026-01-22 10:48:46 +0100)
----------------------------------------------------------------
Memory API patches
- Use explicit endianness for cpu_ld/st_data*() on some targets
- Reduce 'qemu/bswap.h' uses
- Introduce ldm_p/stm_p (MemOp) load/store helpers
- Allow restricting the legacy 'native-endian' APIs
- Forbid various targets to use legacy native endianness APIs
- Simplify cpu_address_space_init() API
----------------------------------------------------------------
