The XY Memory is a feature commonly found in DSP processors to increase
the DSP performance. The XY component allows a ARC processor to
implicitly load source operands and store results into a closely coupled
memory using a single instruction.
Add XY memory for ARC EM9D/EM11D processors including em_starterkit,
em_starterkit_em11d. emsdp_em9d, nsim_em, iotdk.

- update doc for different core configuration.
- fix some bugs in dts related files.
- add dts config and defconfig for different core configuration.
- end files with a newline in boards/arc/emsdp/board.dtsi
- remove unused head in boards/arc/emsdp/doc/index.rst
- ARC_MPU_VER in different core is fixed. so remove some useless code
for ARC_MPU_VER judgements in Kconfig.defconfig.* files for emsdp
