The kernel memtest utility is incredibly useful for detecting memory
problems, but sadly isn't in defconfig.

The memtest itself is only run when the user has explicitly passed a
memtest option on the kernel command line, so simply enabling the option
should not have a negative impact.

Currently when run on an APM platform the ARMv8 defconfig has no viable
options for rootfs other than ramdisk which is rather limiting. Since
we already have both SATA and the bits needed for NFS root enabled we just
need to enable the relevant drivers so do that, helping enable direct
testing of upstream.

If the configuration ends up becoming too big we can consider modularising
some of the drivers and asking people to use an initramfs but for now this
is not an issue.

FPGA implementations of the Cortex-A57 and Cortex-A53 are now available
in the form of the SMM-A57 and SMM-A53 Soft Macrocell Models (SMMs) for
Versatile Express. As these attach to a Motherboard Express V2M-P1 it
would be useful to have support for some V2M-P1 peripherals enabled by
default.

Additionally a couple of of features have been introduced since the last
defconfig update (CMA, jump labels) that would be good to have enabled
by default to ensure they are build and boot tested.

This patch updates the arm64 defconfig to enable support for these
devices and features. The arm64 Kconfig is modified to select
HAVE_PATA_PLATFORM, which is required to enable support for the
CompactFlash controller on the V2M-P1.

A few options which don't need to appear in defconfig are trimmed:

* BLK_DEV - selected by default
* EXPERIMENTAL - otherwise gone from the kernel
* MII - selected by drivers which require it
* USB_SUPPORT - selected by default

Currently, development on arm64 is aided by a Foundation_v8 emulator
distributed by ARM [1]. To run their kernels, users will execute:

  $ ./Foundation_v8 --image linux-system.axf --block-device raring-rootfs

To mount the raring-rootfs filesystem, the kernel parameter should
typically include:

  root=/dev/vda

For this device to be present, the kernel must be compiled with
VIRTIO_{MMIO,BLK}. To make this work out-of-the-box, make it part of the
default configuration.
