[PATCH 8/8] OMAP2+: clockevent: late-init GPTIMER clockevent hwmod right before timer init

[Paul Walmsley]

Late-initialize the GPTIMER hwmod used for the clockevent source immediately
before it is used.  This avoids the need to late-initialize all of the hwmods
until the boot process is further along.  (In general, we want to defer
as much as possible until late in the boot process.)
