MIPS: Loongson 3: Add Lemote-3A machtypes definition

Add four Loongson-3 based machine types:
MACH_LEMOTE_A1004/MACH_LEMOTE_A1201 are laptops;
MACH_LEMOTE_A1101 is mini-itx;
MACH_LEMOTE_A1205 is all-in-one machine.

The most significant differrent between A1004/A1201 and A1101/A1205 is
the laptops have EC but others don't.
