arch/*/configs/*defconfig: Replace AUTOFS4_FS by AUTOFS_FS

Commit a2225d931f75 ("autofs: remove left-over autofs4 stubs")
promised the removal of the fs/autofs/Kconfig fragment for AUTOFS4_FS
within a couple of releases, but five years later this still has not
happened yet, and AUTOFS4_FS is still enabled in 63 defconfigs.

Get rid of it mechanically:

git grep -l CONFIG_AUTOFS4_FS -- '*defconfig' |
xargs sed -i 's/AUTOFS4_FS/AUTOFS_FS/'

Also just remove the AUTOFS4_FS config option stub. Anybody who hasn't
regenerated their config file in the last five years will need to just
get the new name right when they do.

scsi: sr: remove references to BLK_DEV_SR_VENDOR, leave it enabled

This kernel configuration is basically enabling/disabling sr driver quirks
detection. While these quirks are for fairly rare devices (very old CD
burners, and a glucometer), the additional detection of these models is a
very minimal amount of code.

The logic behind the quirks is always built into the sr driver.

This also removes the config from all the defconfig files that are enabling
this already.

powerpc/configs: Disable SCOM_DEBUGFS in powernv_defconfig

SCOM_DEBUGFS is really not needed for anything other than low-level
hardware debugging.

mpe: It also introduces a large and poorly documented/understood
attack surface. Although the interface is only available to root, the
kernel still aspires to restrict root to accessing hardware through
well defined interfaces, which this is not.

opal-prd uses its own interface (/dev/prd) for SCOM access, so it
doesn't need SCOM_DEBUGFS.

At some point in the future we'll introduce a debug config fragment
where this can go instead.

* Turn on async SCSI scanning - Let's see what breaks.
* Add MLX5 driver as a module - Popular demand.
* Add CRYPTO_CRCT10DIF_VPMSUM - POWER8 T10DIF acceleration.

* Make a bunch of USB hid drivers modules.

* Make video drivers except AST GPU modules - Also huge.
* Make PCI serial driver a module - Uncommon.
* Make more things modules, NFS FS, RAM disk, netconsole, MS-DOS fs.

* Get rid of /dev/port - Not used.
* Remove PPS and PTP subsystms - Unusual.
* Remove legacy BSD ttys - Long dead.
* Remove IDE - Deprecated and replaced with ATA.

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.

powerpc/configs: Enable Intel i40e on 64 bit configs

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

powerpc/configs: Change a few things from built in to modules

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

powerpc/configs: Bump kernel ring buffer size on 64 bit configs

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.

powerpc/configs: Enable VMX crypto

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

powerpc: Add MTD_BLOCK to powernv_defconfig

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

powerpc/powernv: Add driver for operator panel on FSP machines

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.

powerpc/powernv: Add 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.
