[PATCH v3 1/3] MIPS: Ingenic: Add Ingenic X1830 support.

From: åçæ (Zhou Yanjie)
Date: Mon Jul 13 2020 - 14:07:30 EST

Support the Ingenic X1830 SoC using the code under arch/mips/jz4740.
This is left unselectable in Kconfig until a X1830 based board is
added in a later commit.

Tested-by: åæ (Zhou Zheng) <sernia.zhou@xxxxxxxxxxx>
Signed-off-by: åçæ (Zhou Yanjie) <zhouyanjie@xxxxxxxxxxxxxx>
---

Notes:
v1->v2:
No change.

v2->v3:
Adjust the order of nodes according to the
corresponding address value.
