MIPS: Fix boot on Fuloong2 systems

Commit 268a2d60013049 ("MIPS: Loongson64: Rename CPU TYPES") changed
Kconfig symbols as follows:
	CPU_LOONGSON2 to CPU_LOONGSON2EF
	CPU_LOONGSON3 to CPU_LOONGSON64
	SYS_HAS_CPU_LOONGSON3 to SYS_HAS_CPU_LOONGSON64

It did not touch SYS_HAS_CPU_LOONGSON2E or SYS_HAS_CPU_LOONGSON2F.
However, the patch changed a conditional from

 #if defined(CONFIG_SYS_HAS_CPU_LOONGSON2E) || \
     defined(CONFIG_SYS_HAS_CPU_LOONGSON2F)

to

 #if defined(CONFIG_SYS_HAS_CPU_LOONGSON2EF)

SYS_HAS_CPU_LOONGSON2EF does not exist, resulting in boot failures
with the qemu fulong2e emulation. Revert to the original code.
