PASEMI: Wrong lscpu info since the RC1 of kernel 6.0

[Christian Zigotzky <chzigotzky@xenosoft.de>]

Hi All,

I use the Nemo board with a PASemi PA6T CPU and some values of lscpu are wrong since the RC1 of kernel 6.0.

One core with 2 threads is wrong. Two cores are correct. Each core has one thread.

Have you modified the detection of the CPU?

Thanks,
