Enable CONFIG_JUMP_LABEL for generic configs in order to better optimize
at runtime and get better test coverage for our jump label support.

In order to have a common code base for fscrypt "post read" processing
for all filesystems which support encryption, this commit removes
filesystem specific build config option (e.g. CONFIG_EXT4_FS_ENCRYPTION)
and replaces it with a build option (i.e. CONFIG_FS_ENCRYPTION) whose
value affects all the filesystems making use of fscrypt.

A couple of patches have come up recently to remove particular instances
of obsolete Kconfig symbols from defconfigs. Rather than doing this
piecemeal, simply regenerate them all.

generic_defconfig explicitly disables CONFIG_INPUT_MOUSEDEV,
CONFIG_INPUT_KEYBOARD & CONFIG_INPUT_MOUSE which results in warnings
when merging board config fragments if any of them require these
options. This is the case for the ranchu board, which means we've had
the following warning when configuring for generic platform targets
since commit f2d0b0d5c171 ("MIPS: ranchu: Add Ranchu as a new
generic-based board"):
$ make ARCH=mips 32r2el_defconfig

Resolve this by removing mention of the CONFIG_INPUT_* Kconfig symbols
from generic_defconfig, allowing them to take their default values &
allowing board config fragments to enable them without warnings.
This may be problematic if CONFIG_ARCH_MIGHT_HAVE_PC_SERIO is ever
enabled for CONFIG_MIPS_GENERIC=y configurations, but for now that isn't
the case so we can worry about that if & when it happens.

In generic_defconfig set CONFIG_NR_CPUS to 16 rather than 2, which is a
rather too low limit for many modern day MIPS systems.

Leave CONFIG_USB_SUPPORT at its default, allowing board config fragments
to make use of USB drivers without needing to override it & trigger
warnings from merge_config.sh.

The generic_defconfig is used for platforms like SEAD3 which do not
usually have fixed storage available, therefore NFS is the preferred
location of the RFS.
When the upstream kernel defconfig is built & tested on platforms such
as SEAD3 this leads to essentially false failures when the RFS fails to
mount.
There is little harm in having this feature enabled by default, so
enable it in the defconfig. Kernel autoconfiguration & DHCP must also be
selected to allow RFS on NFS.

Introduce a "generic" platform, which aims to be board-agnostic by
making use of device trees passed by the boot protocol defined in the
MIPS UHI (Universal Hosting Interface) specification. Provision is made
for supporting boards which use a legacy boot protocol that can't be
changed, but adding support for such boards or any others is left to
followon patches.
Right now the built kernels expect to be loaded to 0x80100000, ie. in
kseg0. This is fine for the vast majority of MIPS platforms, but
nevertheless it would be good to remove this limitation in the future by
mapping the kernel via the TLB such that it can be loaded anywhere & map
itself appropriately.
Configuration is handled by dynamically generating configs using
scripts/kconfig/merge_config.sh, somewhat similar to the way powerpc
makes use of it. This allows for variations upon the configuration, eg.
differing architecture revisions or subsets of driver support for
differing boards, to be handled without having a large number of
defconfig files.
