Merge remote-tracking branch 'agust/next' into next
From Anatolij:
<<
There are cleanups for some mpc5121 specific drivers and DTS files
in preparation to switch mpc5121 clock support to a clock driver
based on common clock framework. Additionally Sebastian fixed the
mpc52xx PIC driver so that it builds when using older gcc versions.
