Subject: [PATCH v2 4/6] MIPS: Move mips_cm_probe after prom_init

Move mips_cm_probe after prom_init so we can use fdt functions
in mips_cm_probe to obtain essential information.

Impat for all systems that may have CM in system:
- geneirc: Adjusted code to accommodate this change
- Lantiq: No impact, CM configuration won't be changed at all
- ralink: Called mips_cm_probe on it's own, in prom_init->prom_soc_init
- malta: Addressed in previous patch
