Clock is enabled only when timer is started and disabled when the the timer
is stopped. Therefore before accessing registers in functions clock is enabled
and then disabled back at the end of access. Context save is done dynamically
whenever the registers are modified. Context restore is called when context is
lost.

Pass the reserved flag in pdata and use it. We can
now make sys_timer_reserved static to mach-omap2/timer.c.

Register timer devices by going through hwmod database using
hwmod API. The driver probes each of the registered devices.
Functionality which are already performed by hwmod framework
are removed from timer code. New set of timers present on
OMAP4 are now supported.

Add routines to converts dmtimers to platform devices. The device data
is obtained from hwmod database of respective platform and is registered
to device model after successful binding to driver.
In addition, capability attribute of each of the timers is added in
hwmod database.

The registers are slightly different between v1 and v2 ip that
is available in omap4 and later for some timers.
Add support for v2 ip by mapping the interrupt related registers
separately and adding func_base for the functional registers.
Also disable dmtimer driver features on omap4 for now as
those need the hwmod conversion series to deal with enabling
the timers properly in omap_dm_timer_init.

If CONFIG_OMAP_32K_TIMER is not selected and dmtimer is used as clocksource, the
timer stops counting once overflow occurs as it was not set in autoreload mode.
This results into timekeeping failure: for example, 'sleep 1' at the shell after
the timer counter overflow would hang.
This patch sets up autoreload when starting the clocksource timer which fixes
the above issue.

We can keep everything sys_timer and gptimer.c related code in
timer.c as the code will be very minimal.
Later on we can also remove timer-mpu.c, as it can be called from
omap4_timer_init function.
This allows us to get rid of confusing existing files. We currently
have timer-gp.c, timer-mpu.c, and patches have been posted to add
dmtimer.c. There's no need to have these multiple files, we can
put everything into timer.c.
