MIPS: loongson64: fix FTLB configuration
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
Fixes: da1bd29742b1 ("MIPS: Loongson64: Probe CPU features via CPUCFG")
