Jamin Lin 80a03b51b2 hw/arm/aspeed_ast27x0: Fix RAM size detection failure on BE hosts 
On big-endian hosts, the aspeed_ram_capacity_write() function previously passed
the address of a 64-bit "data" variable directly to address_space_write(),
assuming host and guest endianness matched.

However, the data is expected to be written in little-endian format to DRAM.
On big-endian hosts, this led to incorrect data being written into DRAM,
which caused the guest firmware to misdetect the DRAM size.

As a result, U-Boot fails to boot and hangs.

- Replaces the "address_space_write()" call with "address_space_stl_le()",
  which performs an explicit 32-bit little-endian write.
- Updating the MemoryRegionOps to restrict access to exactly 4 bytes
  using .valid.{min,max}_access_size = 4 and .impl.min_access_size = 4.
