[PATCH] ARM: OMAP2+: timer: remove CONFIG_OMAP_32K_TIMER

[Igor Grinberg <grinberg@compulab.co.il>]

CONFIG_OMAP_32K_TIMER is kind of standing on the single zImage way.
Make OMAP2+ timer code independant from the CONFIG_OMAP_32K_TIMER
setting.
To remove the dependancy, several conversions/additions had to be done:
1) Timer structures and initialization functions are named by the platform
   name and the clock source in use. The decision which timer is
   used is done statically from the machine_desc structure. In the
   future it should come from DT.
2) Settings under the CONFIG_OMAP_32K_TIMER option are expanded into
   separate timer structures along with the timer init functions.
   This removes the CONFIG_OMAP_32K_TIMER on OMAP2+ timer code.
3) Since we have all the timers defined inside machine_desc structure
   and we no longer need the fallback to gp_timer clock source in case
   32k_timer clock source is unavailable (namely on AM33xx), we no
   longer need the #ifdef around __omap2_sync32k_clocksource_init()
   function. Remove the #ifdef CONFIG_OMAP_32K_TIMER around the
   __omap2_sync32k_clocksource_init() function.

Finally I'm sending this out...
I've lost following Tony's branches and deciding which one to base on,
so I used linux-omap/master as a base for the patch.
Tony, tell me if you want it based on some other branch.
This has been compile tested on omap1|2plus_defconfig only.
