Add initial support for Ingenic X1000 SoC and Y&A CU Neo board.

Add initial support for Ingenic X1000 SoC and Y&A CU Neo board.

[Zhou Yanjie]

1.Add initial Ingenic X1000 SoC support. Provide minimum necessary
  information to boot kernel to an initramfs userspace.
2.CU Neo is a development board using Ingenic X1000/X1000E SoC. It
  comes with either 32MiB/64MiB of RAM. Add initial support for
  CU Neo development board.

[PATCH 1/4] MIPS: Ingenic: initial X1000 support.

[Zhou Yanjie]

Support the Ingenic X1000 SoC using the code under arch/mips/jz4740.
This is left unselectable in Kconfig until a X1000 based board is
added in a later commit.

That code was removed in the TCU patchset that was merged in time for 
5.4-rc1.
Please rebase your patchset on top mips-next.
