MIPS: Fix MIPS I ISA /proc/cpuinfo reporting
Correct a commit 515a6393dbac ("MIPS: kernel: proc: Add MIPS R6 support
to /proc/cpuinfo") regression that caused MIPS I systems to show no ISA
levels supported in /proc/cpuinfo, e.g.:
system type : Digital DECstation 2100/3100
machine : Unknown
processor : 0
cpu model : R3000 V2.0 FPU V2.0
BogoMIPS : 10.69
wait instruction : no
microsecond timers : no
tlb_entries : 64
extra interrupt vector : no
hardware watchpoint : no
isa :
ASEs implemented :
shadow register sets : 1
kscratch registers : 0
package : 0
core : 0
VCED exceptions : not available
VCEI exceptions : not available
and similarly exclude `mips1' from the ISA list for any processors below
MIPSr1. This is because the condition to show `mips1' on has been made
`cpu_has_mips_r1' rather than newly-introduced `cpu_has_mips_1'. Use
the correct condition then.
