linux-next: manual merge of the arm-soc tree with the arm tree

Hi all,

Today's linux-next merge of the arm-soc tree got a conflict in
arch/arm/plat-omap/counter_32k.c between commit bd0493eaaf5c ("ARM:
7413/1: move read_{boot,persistent}_clock to the architecture level")
from the arm tree and commit 1fe97c8f6a1d ("ARM: OMAP: Make OMAP
clocksource source selection using kernel param") from the arm-soc tree.

I attempted to fix it up (see below) and can carry the fix as necessary.

Cheers,
