Subject: [PATCH 4/4] MIPS: loongson64: fix FTLB configuration

Commit "da1bd29742b1" ("MIPS: Loongson64: Probe CPU features via
CPUCFG") makes 'set_ftlb_enable' called under c->cputype unset,
which leaves FTLB disabled on BOTH 3A2000 and 3A3000

Fixes: da1bd29742b1 ("MIPS: Loongson64: Probe CPU features via CPUCFG")
