mips: drop selecting non-existing config NR_CPUS_DEFAULT_2

Commit c5eaff3 ("MIPS: Kconfig: Drop obsolete NR_CPUS_DEFAULT_{1,2}
options") removed the config NR_CPUS_DEFAULT_2, as with this commit, the
NR_CPUS default value is 2.

Commit 7505576 ("MIPS: add support for SGI Octane (IP30)") introduces
the config SGI_IP30, which selects the removed config NR_CPUS_DEFAULT_2,
but this has actually no effect.

Fortunately, NR_CPUS defaults to 2 when there is no specific
NR_CPUS_DEFAULT_* config selected. So, the effect of the intended
'select NR_CPUS_DEFAULT_2' is achieved without further ado.

Drop selecting the non-existing config NR_CPUS_DEFAULT_2.

The issue was identified with ./scripts/checkkconfigsymbols.py.
