Merge tag 'arc-updates-for-2018.07-rc1' of git://git.denx.de/u-boot-arc

Here we do a couple of minor fixes like:
 - Move .ivt section to the very beginning of the image
   by default which allows us to use that image put right
   at reset vector (usually 0x0)

 - Improve relocation fix-up which became required once
   we moved .ivt and understood a problem with existing implementation
   where we relied on a particular placement of sections.
   Now we don't care about placement because we just explicitly
   check for .text and in case of ARCompact .ivt sections

 - Re-implemnt do_reset() such that it calls reset_cpu() which
   could implmented for a particular board

And hte most important part we introduce support for yet another
devboard from Synopsys - EMDK.
