MIPS: Fix MIPS I ISA /proc/cpuinfo reporting

Browse Source 
commit e5f5a5b06e51a36f6ddf31a4a485358263953a3d upstream.

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.
