[PULL 14/34] hw/char/serial: Let compiler pick serial_mm_ops[] array length

Posted by Philippe Mathieu-Daudé 1 week ago

No need to enforce the MemoryRegionOps array length.
We index by device_endian enum, the compiler will easily
pick the correct length. Besides, this allow further
adjustments in the device_endian enum itself.
