[U-Boot] Please pull ARC changes

[Alexey Brodkin]

Hi Tom,

Seems like I'm a little bit late as RC1 was already cut but anyways
I think most if not all the mentioned below changes could be safely pulled.

That's because 5 of 6 patches are really just very trivial fixes
(which I think is quite of for post-RC1 stage) and the only more significant
change is HSDK clk driver. Still that patch was floated on the mailing list
quite some time ago and shouldn't cause any troubles because it is by default
is disabled, and essentially it all went through full TravisCI build so
I don't expect any issues.

Anyways if you prefer I may exclude HSDK clk driver from this pull-request and
resend it shortly.

The following changes since commit 335f7b1290ce24a729a9689a1db834c743226ca8:
