Per the Armv7-M Architecture Reference Manual (ARM DDI 0403E):
The System Control Space (SCS, address range 0xE000E000 to
0xE000EFFF) is a memory-mapped 4KB address space that provides
32-bit registers for configuration, status reporting and control.
All accesses to the SCS are little endian.
Expose the region as a little-endian one and force dispatched
accesses to also be in little endianness.

What's the rationale for this change? All Arm system emulator
builds are TARGET_LITTLE_ENDIAN, so MO_TE and MO_LE have
identical behaviour, as do DEVICE_LITTLE_ENDIAN and
DEVICE_TARGET_ENDIAN.
