MIPS: loongson64: fix FTLB configuration
[ Upstream commit 7db5e9e9e5e6c10d7d26f8df7f8fd8841cb15ee7 ]
It turns out that 'decode_configs' -> 'set_ftlb_enable' is called under
c->cputype unset, which leaves FTLB disabled on BOTH 3A2000 and 3A3000
Fix it by calling "decode_configs" after c->cputype is initialized
