The generic MIPS system type allows building a board agnostic kernel and
should be the default starting point for users, so set it as the default
system type in Kconfig.
Since ip22 is no longer the default, update ip22_defconfig to select
CONFIG_SGI_IP22.

This patch "fixes" the build errors reported by kernelci.org for the
allnoconfig, generic_defconfig and tinyconfig targets.
There is another workaround for the actual build failure in patchwork
here https://patchwork.linux-mips.org/patch/14397/, but since that patch
just works around a toolchain bug it is not ideal either. Since
toolchains that produce failures here are out in the wild, banning
binutils 2.25 & 2.26 doesn't seem helpful as that will just trigger more
problems.
So perhaps the best thing to do is to update the default system to
something which does not suffer the issue and is additionally more modern
and actively maintained.

The default system type should be a MIPS generic kernel. In order to
include some level of board support, select a 32r2el generic defconfig
by default. The alternative would be to use "generic_defconfig" but
rather unintuitvely that is a bare bones configuration with no platform
support so is not usable in practice.

Thanks, both patches applied for 4.15.
