Subject: [PATCH] ARM: OMAP2+: Regression: Add missing code while merging commit ff931c82 to Mainline

While merging commit ff931c82 [1] to Mainline,, it seems not all the changes from 
the original patch [2] have been merged; changes from mach-omap2/timer.c have been
dropped, which invokes xxx_clk_init() function required to register platform
clock table. And without this none of OMAP family of devices will boot from
Mainline.
