configs:ks2_evm: update defconfigs to support SPL

The K2HK and K2E boards support SPL by default, so add
CONFIG_SPL option. Also export CONFIG_ARM, CONFIG_ARCH_KEYSTONE
and TARGET_K2*_EVM options to spl/.config as they are the same.
So now it's convinient to build gph images using only two commands:

make k2hk_evm_defconfig
make u-boot-spi.gph

ks2_evm: readme: align according to actual sources

Update readme file for Keystone II EVM boards to actual sources.
Also correct some typos. For now the Edison evaluation board is
added, README for K2E is mostly the same, so update README to
contain information also for K2E evm. Rename file to README as
it contains information for all keystone evm boards.

tools: compiler.h: Fix build on FreeBSD

Commit 832472 "tools: socfpga: Add socfpga preloader signing
to mkimage" added tools/socfpga.c which relies on htole32,
le32toh and friends. While compiler.h includes these protypes
for linux from endian.h, it doesn't do so for FreeBSD. Hence
include <sys/endian.h> for FreeBSD.

Makefile: drop "tools-only" from no-dot-config-targets

With the introduction of CONFIG_LOCALVERSION support we cannot build
tools without having a config file (as we won't know our PLAIN_VERSION
until then).

sunxi: axp152: dcdc3 scale is 50mV / step not 25mV / step

Currently uboot wrongly uses 25mV / step for dcdc3, this is a copy and paste
error introduced when adding the axp152_mvolt_to_target during review of the
axp152.c driver. This results in u-boot setting Vddr to 2.3V instead of 1.5V.

This commit fixes this.

wandboard: Use 32bit color depth for Fusion LCD

The Fusion LCD needs the 32bit color depth to properly work; the
default is different on the 3.10.17 kernels and it is better to ensure
it work out of box using proper default color setting.
