[PATCH v2 8/8] ARM: OMAP2+: timer: use a proper interface to get hwmod data

arch/arm/mach-omap2/timer.c pokes around inside the hwmod data
structures. Since the hwmod data structures are about to change, this
code will break. This patch modifies the timer code to use
recently-added hwmod functions instead.
