These changes is the result of the discussion with Paul Walmsley.
His ideas are included into this patch.
Remove DPLL output divider handling from DPLLs and CLKOUTX2 clocks,
and place it into specific DPLL output divider clocks (e.g., dpll3_m2_clk).
omap2_get_dpll_rate() now returns the correct DPLL rate, as represented
by the DPLL's CLKOUT output. Also add MPU and IVA2 subsystem clocks, along
with high-frequency bypass support.
Add support for DPLLs function in locked and bypass clock modes.

This patch changes 24xx to use shared clock code and new register

Note that patch adds some temporary OLD_CK defines to keep patch

This patch changes 24xx to use new register access, except for clock
framework. Clock framework register access will get updates in the
next patch.
Note that board-*.c files change GPMC (General Purpose Memory Controller)
access to use gpmc_cs_write_reg() instead of accessing the registers
directly. The code also uses gpmc_fck instead of it's parent clock
core_l3_ck for GPMC clock.
The H4 board file also adds h4_init_flash() function, which specify the
flash start and end addresses.
Also note that sleep.S removes some unused registers addresses.

Remove MPU-timer based sched_clock() in favor of the common one based

Since 32k timer code is moving to OMAP1 specific dir, move the
32k-based sched_clock() into common code where it is based on the 32k
sync counter and can be used even when using MPU timer.
While moving, change the ticks-to-nsecs conversion to use the helper
functions provided by clocksource.h.
Also removed the unused ticks_to_usec, leaving only ticks_to_nsec.

On OMAP2/3, the gp-timer code can be used for a 32kHz timer simply by
setting the source to be the 32k clock instead of sys_clk.
This patch uses the mach-omap2/timer-gp.c code for 32kHz timer on
OMAP2, moving the logic into mach-omap2/timer-gp.c, and not using
plat-omap/timer32k.c which, for OMAP2, is redundant with the timer-gp
code.
Also, if CONFIG_OMAP_32K_TIMER is enabled, the gptimer-based
clocksource is not used. Instead the default 32k sync counter is used
as the clocksource (see the clocksource in plat-omap/common.c.) This
is important for sleep/suspend so there is a valid counter during
sleep. Note that the suspend/sleep code needs fixing to check for
overflows of this counter.
In addition, the OMAP2/3 details are removed from timer32k.c leaving
that with only OMAP1 specifics. A follow-up patch will move it from
plat-omap common code to mach-omap1.

Currently, the GPIO interrupt handling is duplicating some of the work
done by the generic IRQ handlers (handle_edge_irq, handle_level_irq)
such as detecting nesting, handling re-triggers etc. Remove this
duplication and use generic hooks based on IRQ type.
Using generic IRQ handlers ensures correct behavior when using
threaded interrupts introduced by the -rt patch.

The clearing was moved to the unmask hook because it is known to run
after the interrupt handler has actually run. Before this patch, if
interrupts are threaded, the clearing/unmasking of level triggered
interrupts would be done before the threaded handler actually ran.
