That's because we missing a timer1 hwmod data structure
in arch/arm/mach-omap2/omap_hwmod_44xx_data.c
But in arch/arm/mach-omap2/timer-gp.c:266, it try to setup a timer1
omap_hwmod.

We can ignore the omap_hwmod_setup_one in timer-gp.c, but I'm not sure about
that.
In arch/arm/mach-omap2/omap_hwmod_44xx_data.c:573:
--
/*
 * Modules omap_hwmod structures
 *
 * The following IPs are excluded for the moment because:
 * - They do not need an explicit SW control using omap_hwmod API.
 * - They still need to be validated with the driver
 *   properly adapted to omap_hwmod / omap_device
 *
....
 * timer1

It looks like we don't have timer1 hwmod for timer-gp.c.

Sebastien, could you help to take a look at this? or we can post this to
upstream.

Should we setup some config files in user space?
