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.
Signed-off-by: Zhou Yanjie <[email protected]>

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.
