[PATCH v2 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.

Notes:
    v1->v2:
    Rebase on top of mips-next, use ingenic-timer driver
    for system timer and clocksource.
