Subject: [PATCH v5 04/10] MIPS: Ingenic: Initial YSH & ATIL CU Neo board support.
Add a device tree for the Ingenic X1000 based YSH & ATIL CU Neo board.
Note that this is unselectable via Kconfig until the X1000 SoC is made
selectable in a later commit.
Signed-off-by: Zhou Yanjie <zhouyanjie@...o.com>

Notes:
v1->v2:
Rebase on top of mips-next, use TCU for system timer and clocksource.
v2->v3:
No change.
v3->v4:
1.Adjust "model" in "cu1000.dts" to match the description in "devices.yaml".
2.Adjust "bool" in "Kconfig" to avoid duplicate names with subsequent boards.
v4->v5:
1.Rename "cu1000" to "cu1000-neo" to prevent conflicts with subsequent boards
such as "cu1000-geo", and so on.
2.Remove "CONFIG_HZ=100" and "mem=32M@0x0" from defconfg.
3.Modify incorrect comments in DT.
