[U-Boot] [PATCH] cpu: bmips: fix probe to get the address

[U-Boot] [PATCH] cpu: bmips: fix probe to get the address

[Philippe Reynes]

In the device tree, the address for cpu is located in
the node "cpus", not in the cpu node (for exemple cpu at 0).
So when probing cpu, the cpu address must be read in the
cpu parent.

The commit "cpu: bmips: convert to use live dt"
(sha1: c444afbbefa103d567f197393d39ec0fcca21a0c)
change this behaviour and read the address in the
cpu node when probing cpu.

We fix this by reading the address in the cpu parent.
