Subject: [PATCH v2] MIPS: Ingenic: Add system type for new Ingenic SoCs.

Add JZ4730, JZ4750, JZ4755, JZ4760, JZ4760B, X2000H, and X2100 system
type for cat /proc/cpuinfo to give out JZ4730, JZ4750, JZ4755, JZ4760,
JZ4760B, X2000H, and X2100.

Notes:
    v1->v2:
    1.Add system type for JZ4750 and JZ4755 as Paul Cercueil's suggestion.
    2.Add Paul Cercueil's Reviewed-by.
