As mentioned in LTP's README.ARC:
------------->8------------
Requirements for the environment
* Linux must be built with support of loop block devices. Thus it's
necessary to enable these Linux kernel options:
CONFIG_BLK_DEV
CONFIG_BLK_DEV_LOOP
------------->8------------
enabling loop block devices.
That among other things lead to additional 10 fatal signals
appearing during LTP run.

The problem is with CONFIG_CPU_BIG_ENDIAN=y we still needed .config
fixup to override the the defconfig prefix to arceb-linux-
So remove these from defconfig and let user pass this via CROSS_COMPILE
environment var or use the default for ENDIAN (per previous patch)
No other arch carries them in defconfigs anyways !

Even though DEVTMPFS is required when our pre-built initramfs
is used it is not the case in general. It is perfectly possible
to use initramfs with device nodes already populated or there
could be other usages, see discussion below for more detials:
http://thread.gmane.org/gmane.comp.embedded.openwrt.devel/37819/focus=37821
This change removes mentioned dependency from arch/arc/Kconfig
updating instead those defconfigs that are usually used with this
kind of pre-build initramfs.
And while at it all touched defconfigs were regenerated via
savedefconfig and some options were removed:
* USB is selected by other options implicitly
* VGA_CONSOLE is disableb for ARC since
031e29b587
* EXT3_FS automatically selects EXT4_FS
* MTDxxx and JFFS2_FS make no sense for AXS because
AXS NAND controller is not upstreamed
* NET_OSCI_LAN is not in upstream as well
* ARCPGU_xxx options make no sense because ARC PGU is not yet
in upstream and when it gets there all config options would
be taken from devicetree

When building kernel with buildroot built toolchain, CROSS_COMPILE
currently needs adjustment even if minor. This is because the defconfigs
prefer "arc-linux-uclibc-" prefix from hand built (non buildroot) toolchain
while buildroot provides "arc-buildroot-linux-uclibc-"
To avoid this use the common "arc-linux-" prefix which is provided by
buildroot and has also been in hand built tools for quite some time.

[vgupta: updated changelog]
DesignWare MMC Controller's transfer mode should be decided
at runtime instead of compile-time. So we remove this config
option and read dw_mmc's register to select DMA master.
