As we discussed a couple of times, negative CONFIG options make our
life difficult; CONFIG_SYS_NO_FLASH, CONFIG_SYS_DCACHE_OFF, ...
and here is another one.

Now, there are three boards enabling OF_CONTROL on SPL:
 - socfpga_arria5_defconfig
 - socfpga_cyclone5_defconfig
 - socfpga_socrates_defconfig

This commit adds CONFIG_SPL_OF_CONTROL for them and deletes
CONFIG_SPL_DISABLE_OF_CONTROL from the other boards to invert
the logic.

Since commit a26cd049 ("arch: Make board selection choices
optional"), Kconfig could create such an insane .config file that
no SoC/board is selected.

This is now a real problem for Buildroot, for example.
(http://lists.busybox.net/pipermail/buildroot/2015-July/135125.html)

This commit drops the "optional" from the ARM target select menu
in favor of "Versatile family".

Rationale:
 - Historically, Linux chose versatile_defconfig as the default
   of ARM defconfig. (arch/arm/Makefile of Linux describes:
   KBUILD_DEFCONFIG := versatile_defconfig)

 - It was published by ARM Ltd.

HiKey is the first 96boards consumer edition compliant board. It features a hi6220
SoC which has eight ARM A53 cpu's.

This initial port adds support for: -
1) Serial
2) eMMC / SD card
3) USB
4) GPIO

It has been tested with Arm Trusted Firmware running u-boot as the BL33 executable.

Notes:

eMMC has been tested with basic reading of eMMC partition into DDR. I have not
tested writing / erasing. Due to lack of clock control it won't be
running in the most performant high speed mode.

SD card slot has been tested for reading and booting kernels into DDR.
It is also currently configured to save the u-boot environment to the
SD card.

USB has been tested with ASIX networking adapter to tftpboot kernels
into DDR. On v2015.07-rc2 dhcp now works, and also USB mass storage
are correctly enumerated.

GPIO has been tested using gpio toggle GPIO4_1-3 to flash the LEDs.
