board: emsdp: doc update and bug fixes

- 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
