ARM: OMAP: timer: obey the !CONFIG_OMAP_32K_TIMER

commit 45caae74d238ef6583e9402cb8c550cc0b0f7dbd upstream.

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.
