x86: cpu: Use default print_cpuinfo() for all

Most of the copies of the print_cpuinfo() call the default method.
Remove all of those in order to have only the default one when
no `cpu` command is compiled.

This also helps avoiding compiler warning, e.g.:

  arch/x86/cpu/tangier/tangier.c:23:5: warning: no previous prototype for ‘print_cpuinfo’ [-Wmissing-prototypes]
