A couple fixups to get OMAP3 working again after my previous 32k
sync timer updates.
Tested on 3430SDP and 2430SDP.

[-- Type: text/plain, Size: 865 bytes --]
When CONFIG_OMAP_RESET_CLOCKS=y is enabled on OMAP3, the 32k sync
clock is disabled, resulting in a crash when any access to it is done,
including a sched_clock().
