Currently, omap2_sync32k_clocksource_init() function initializes the 32K
timer as the system clock source regardless of the CONFIG_OMAP_32K_TIMER
setting.
Fix this by providing a default implementation for
!CONFIG_OMAP_32K_TIMER case.

Thanks Santosh!

Tony, apparently, this bug has been there for a while,
so probably I should have added:
Cc: stable@vger.kernel.org

Thanks!

Thanks I'll apply this into fixes with Cc: stable. Note that
Cc: stable is usually added at commit time, or at least you're
not supposed to send the patch for review there.
