Enable CONFIG_KEXEC_FILE in powernv_defconfig, ppc64_defconfig and
pseries_defconfig.
It depends on CONFIG_CRYPTO_SHA256=y, so add that as well.

These are the PPC optimised versions of various crypto algorithms, so we
should turn them on by default to get test coverage.

No one uses reiserfs much these days, or is likely to in future. So drop
it from pseries and powernv defconfigs to save time and space. It's
still enabled in ppc64_defconfig so we get some build coverage.

We are starting to see i40e adapters in recent machines, so enable
it in our configs.

Change a few devices and filesystems that are seldom used any more
from built in to modules. This reduces our vmlinux about 500kB.

When we issue a system reset, every CPU in the box prints an Oops,
including a backtrace. Each of these can be quite large (over 4kB)
and we may end up wrapping the ring buffer and losing important
information.
Bump the base size from 128kB to 256kB and the per CPU size from
4kB to 8kB.

We see big improvements with the VMX crypto functions (often 10x or more),
so enable it as a module.

This is so we can use the powernv_flash mtd driver as an block

Implement new character device driver to allow access from user space
to the operator panel display present on IBM Power Systems machines
with FSPs.
This will allow status information to be presented on the display which
is visible to a user.
The driver implements a character buffer which a user can read/write
by accessing the device (/dev/op_panel). This buffer is then displayed on
the operator panel display. Any attempt to write past the last character
position will have no effect and attempts to write more characters than
the size of the display will be truncated. The device may only be accessed
by a single process at a time.

There are a few firmware-provided interfaces for OpenPOWER platforms:
the PRD infrastructure, IPMI support, and MTD access to the PNOR flash.
This change adds these to powernv_defconfig

This change adds a defconfig for the non-virtualised power platforms,
based on pseries_defconfig, but without pseries, and little-endian,
and no OF trampoline.
