[PATCH v3 06/15] MIPS: generic: Allow boards to set system type

[Paul Cercueil]

Check for the (already existing) "system_type" variable in the
get_system_type() function. If non-NULL, return it as the system type.

Signed-off-by: Paul Cercueil <paul@xxxxxxxxxxxxxxx>

Notes:
    v2: Instead of adding a .get_system_type callback to the mips_machine
    	struct, the boards now simply override the "system_type" variable
    	when they want to set a custom one.
    
    v3: No change
