[PATCH] MIPS: cpu-probe: Recognise the XBurst core of the Ingenic X1600

[Olivier Louvignes]

The X1600 reports PRId 0x00d00000: company Ingenic D0, implementation 0,
which cpu_probe_ingenic() rejects with "Unknown Ingenic Processor ID!"
before any console exists. It is an XBurst1 core like the X1830's, which
shares the D0 company ID, so handle it the same way.

Tested on a HiBy R1 (X1600), which boots v7.3 with this.
