[PATCH] ARM: OMAP2: use correct timer function for AM43XX and TI81XX

[arnd@arndb.de (Arnd Bergmann)]

AM43XX and TI81XX use omap3_gptimer_timer_init(), but that is only
built into the kernel for OMAP3 and AM33XX, otherwise we get:

arch/arm/mach-omap2/built-in.o:(.arch.info.init+0x124): undefined reference to `omap3_gptimer_timer_init'

This changes the Kconfig logic for building the function to
match the callers. Consequently, we no longer need to build
the omap3_secure_sync32k_timer_init and omap4_local_timer_init
for the platforms that have been moved over to other functions.

Signed-off-by: Arnd Bergmann <arnd@arndb.de>

The code has changed a couple of times, but this version no longer
produces build errors for me.
