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.
    
    v2->v3:
    Drop the 'apb' node.
    
    v3->v4:
    Adjust the node order to make it consistent with
    other Ingenic boards.
