MIPS: Loongson: Lemote-2F: Get the machine type from PMON_VER

Browse source 
Lemote have used the PMON_VER strings to indicate the loongson-2f
machine series:

 	PMON_VER=LM8089		Lemote 8.9'' netbook
 	         LM8101		Lemote 10.1'' netbook
 	(The above two netbooks have the same kernel support)
	         LM6XXX		Lemote FuLoong(2F) box series
	         LM9XXX		Lemote LynLoong PC series

Before the machtype is supported by the PMON, we can get the machine
type from the PMON_VER for these machines, this will help the users a
lot.
