[PATCH v2 01/19] MIPS: Loongson64: Rename CPU TYPES

[Jiaxun Yang <jiaxun.yang@flygoat.com>]

CPU_LOONGSON2 -> CPU_LOONGSON2EF
CPU_LOONGSON3 -> CPU_LOONGSON64

As newer loongson-2 products (2G/2H/2K1000) can share kernel
implementation with loongson-3 while 2E/2F are less similar with
other LOONGSON64 products.
