arc: get rid of DEVTMPFS dependency on INITRAMFS_SOURCE

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 031e29b * 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 Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com> Signed-off-by: Vineet Gupta <vgupta@synopsys.com>
